2010-05-14drivers/net: Remove unnecessary returns from void function()sJoe Perches
This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand. Compile tested x86 allmodconfig only. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

"iwl: cleanup: remove unneeded error handling" missed the one in if_sdio_debugfs_init().

2010-04-28iwl: cleanup: remove unneeded error handlingDan Carpenter
This is just a cleanup and doesn't change how the code works. debugfs_create_dir() and debugfs_create_file() return an error pointer (-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs they return NULL. This is how they are implemented and what it says in the DebugFS documentation. DebugFS can not be compiled as a module. As a result, we only need to check for error pointers and particularly -ENODEV one time to know that DebugFS is enabled. This patch keeps the first check for error pointers and removes the rest. The other reason for this patch, is that it silences some Smatch warnings. Smatch sees the condition "(result != -ENODEV)" and assumes that it's possible for "result" to equal -ENODEV. If it were possible it would lead to an error pointer dereference. But since it's not, we can just remove the check. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: John W.

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.

2009-11-28iwmc3200wifi: 802.11n Tx aggregation supportSamuel Ortiz
To support 802.11n Tx aggregation support with iwmc3200 wifi, we have to handle the UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification from the UMAC. Before sending an AddBA, the UMAC synchronizes with the host in order to know what is the last Tx frame it's supposed to receive before it will be able to start the actual aggregation session. We thus have to keep track of the last sequence number that is scheduled for transmission on a particular RAxTID, send an answer to the UMAC with this sequence number. The UMAC then does the BA negociation and once it's done with it sends a new UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification to let us know that we can resume the Tx flow on the specified RAxTID.
