2010-04-07device_attributes: add sysfs_attr_init() for dynamic attributesWolfram Sang
Made necessary by 6992f5334995af474c2b58d010d08bc597f0f2fe ("sysfs: Use one lockdep class per sysfs attribute"). Prevents further "key xxx not in .data" bug-reports. Although some attributes could probably be converted to static ones, this is left for people having hardware to test. Found by this semantic patch: @ init @ type T; identifier A; @@ T { ... struct device_attribute A; ... }; @ main extends init @ expression E; statement S; identifier err; T *name; @@ ... when != sysfs_attr_init(&name->A.attr); ( + sysfs_attr_init(&name->A.attr); if (device_create_file(E, &name->A)) S | + sysfs_attr_init(&name->A.attr); err = device_create_file(E, &name->A); ) While reviewing, I put the initialization to apropriate places.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-03-07media: move omap24xxcam's probe function to .devinit.textUwe Kleine-König
A pointer to omap24xxcam_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

2010-02-26V4L/DVB: gscpa_sonixb: Differentiate between sensors with a coarse and fine ↵Hans de Goede
expo ctrl Some sensors only allow controlling the exposure by changing the clockdiv, which means that exposure takes pretty large jumps (for example when going from a div of 1 to 2, the exposure doubles). Use 2 different entries in the controls array for these 2 different types of exposure (always disabling one), and; Add a new autogain algorithm for the coarse exposure case, which normally changes the gain setting, only touching the exposure setting if the desired luminance cannot be reached with gain, and after an exposure change once more first tries gain, etc. Thus avoiding exposure changes, and the resulting oscilation because of the huge steps these exposure controls take.

This is a slightly modified version of Eric Anderson's original patch for the Sony Giga Pocket board.

Also Andy Walls modified the patch to use a new Sony BTF-Pnx01Z tuner entry based on Eric Anderson's experimental findings for the bandswitch. >From Eric Anderson's original email: 1. The tuner on the card doesn't seem to match any standard ones. I modified an existing tuner entry. Ideally a new tuner entry should be created. (The only difference from the one I modified is that the low-to-mid range frequency cut-off is slightly different, as are the bit config settings.) 2. It wasn't obvious how to choose a second audio input other than using "radio" as an option. Basically there's two GPIO audio inputs. Using radio allowed me to avoid major restructuring to the code. (perhaps other cards don't have this often...) 3. It's not clear that there's a mute setting that works. Not sure why. 4. I haven't had a chance to test the two Svideo inputs. I set them to COMPOSITE1 and SVIDEO2, but I'm not sure those are the correct settings. The standard composite video inputs seem to work.
