Mark variables in drivers/* with uninitialized_var() if such a warning appears, and analysis proves that the var is initialized properly on all paths it is used. Signed-off-by:Jeff Garzik <jeff@garzik.org>

An uninitialized variable warning illuminated an area where indeed the variable was being used without initialization. Unfortunately, after verifying all such paths were fixed, the warning still appears. So we follow the initialization practice of other variables in this function. Signed-off-by: -

drivers/infiniband/hw/mthca/mthca_qp.c: In function ‘mthca_tavor_post_send’: drivers/infiniband/hw/mthca/mthca_qp.c:1594: warning: ‘f0’ may be used uninitialized in this function drivers/infiniband/hw/mthca/mthca_qp.c: In function ‘mthca_arbel_post_send’: drivers/infiniband/hw/mthca/mthca_qp.c:1949: warning: ‘f0’ may be used uninitialized in this function Initializing 'f0' is not strictly necessary in either case, AFAICS. I was considering use of uninitialized_var(), but looking at the complex flow of control in each function, I feel it is wiser and safer to simply zero the var and be certain of ourselves.

It's actually convenient in the code to initialize this and a sister variable to zero. Signed-off-by: -

1) Fix gcc uninit'd var warnings by adding 'default' switch stmt labels in two cases. It was lightning-strikes unlikely that a problem would ever arise, but not impossible. 2) Tighten the scope of 'blankword' in two cases. Signed-off-by: -

The warning drivers/net/wan/pc300_drv.c: In function ‘cpc_open’: drivers/net/wan/pc300_drv.c:2942: warning: ‘br’ may be used uninitialized in this function was valid. Ensure 'br' is initialized in all cases. Signed-off-by: -

1) We should only set 'actual_length' output variable if usb length is known to be good. 2) No need to check actual_length for NULL. The only caller always passes non-NULL value. Signed-off-by: -

This episode illustrates how an overused warning can train people to ignore that warning, which winds up hiding bugs. The warning drivers/net/natsemi.c: In function ‘natsemi_remove1’: drivers/net/natsemi.c:3222: warning: ignoring return value of ‘device_create_file’, declared with attribute warn_unused_result is oft-ignored, even though at close inspection one notices this occurs in the /remove/ function, not normally where creation occurs. A quick s/create/remove/ and we are fixed, with the warning gone. Signed-off-by: -

Kill this warning... kernel/auditfilter.c: In function ‘audit_receive_filter’: kernel/auditfilter.c:1213: warning: ‘ndw’ may be used uninitialized in this function kernel/auditfilter.c:1213: warning: ‘ndp’ may be used uninitialized in this function ...with a simplification of the code. audit_put_nd() can accept NULL arguments, just like kfree(). It is cleaner to init two existing vars to NULL, remove the redundant test variable 'putnd_needed' branches, and call audit_put_nd() directly. As a desired side effect, the warning goes away.

Verify that types would match for assignment (under sizeof, so we are safe from side effects or any code actually getting generated), then explicitly cast everywhere to the fixed-sized types. Kills a bunch of bogus warnings about constants being truncated (gcc, sparse), finds a pile of endianness problems hidden by old noise (sparse). Signed-off-by:

bitmap_unplug only ever returns 0, so it may as well be void. Two callers try to print a message if it returns non-zero, but that message is already printed by bitmap_file_kick. write_page returns an error which is not consistently checked. It always causes BITMAP_WRITE_ERROR to be set on an error, and that can more conveniently be checked. When the return of write_page is checked, an error causes bitmap_file_kick to be called - so move that call into write_page - and protect against recursive calls into bitmap_file_kick. bitmap_update_sb returns an error that is never checked. So make these 'void' and be consistent about checking the bit. Signed-off-by:

We current completely trust user-space to set up metadata describing an consistant array. In particlar, that the metadata, data, and bitmap do not overlap. But userspace can be buggy, and it is better to report an error than corrupt data. So put in some appropriate checks. Signed-off-by:

Don't use 'unsigned' variable to track sync vs non-sync IO, as the only thing we want to do with them is a signed comparison, and fix up the comment which had become quite wrong. Signed-off-by:

Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This includes voltage regulators, Dual slot memory card tranceivers and real-time clock(RTC). The support for RTC is integrated with this driver only; it is not separate module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic" (1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too. The battery keeps the RTC active over power off, so once you set clock (rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will behave as expected.
