2009-07-28libata: remove superfluous NULL pointer checksBartlomiej Zolnierkiewicz
host->ports[] always contain pointers to valid port structures since a "dummy port" structure is used in case if there is no physical port. This patch takes care of two entries from Dan's list: drivers/ata/sata_sil.c +535 sil_interrupt(13) warning: variable derefenced before check 'ap' drivers/ata/sata_mv.c +2517 mv_unexpected_intr(6) warning: variable derefenced before check 'ap' and of another needless NULL pointer check in pata_octeon_cf.c.

drivers/ata/libata-eh.c +2403 ata_eh_reset(80) warning: variable derefenced before check 'slave' Please note that this is _not_ a real bug at the moment since ata_eh_context structure is embedded into ata_list structure and the code alwas checks for 'slave' before accessing 'sehc'. Anyway lets add missing check and always have a valid 'sehc' pointer (which makes code easier to understand and prevents introducing some possible bugs in the future).

I've tested TSL2550 driver and I've found a bug: when light is off, returned value from tsl2550_calculate_lux function is -1 when it should be 0 (sensor correctly read that light was off). I think the bug is that a zero c0 value (approximated value of ch0) is misinterpreted as an error.

This fixes - locking bug that was hidden by ecc2e05e739c30870c8e4f252b63a0c4041f2724 - Regression #13821 - Spurious warning when closing and blocking for data write out With these changes my PL2303 always ends up as ttyUSB0 when it should and the module refcounts stay correct. I'll do a more wholesale split & tidy of _open in the next release or two as we get a standard tty_port_open and port->ops->init port->ops->shutdown call backs.

The port lock is used to protect the port state. However the port structure is freed on a hangup, then the lock taken on a close. The right fix is to drop the port on tty->shutdown() but we can't yet do that due to sleep v non-sleeping rules. Instead do the next best thing and fix it up when we are not in -rc season.

When a net device goes down or when the bnx2i driver is unloaded, the code was not generating the ISCSI_KEVENT_IF_DOWN message properly and this could cause the userspace driver to crash.

In order to properly estimate fps, mt9v011 sensor driver needs to know what is the used frequency on the sensor cristal. Adds the proper fields and initialization code for specifying the cristal frequency. Also, based on experimentation, it was noticed that the Silvercrest is outputing data at 7 fps. This means that it should be using a 6.3 MHz cristal. This information needs to be double checked later, by opening the device. Anyway, by using this value for xtal, at least now we have the correct fps report. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
