2020-07-16treewide: Remove uninitialized_var() usageKees Cook1-2/+2
Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space. No outstanding warnings were found building allmodconfig with GCC 9.3.0 for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64, alpha, and m68k.

Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2012-12-06ssb: add methods for watchdog driverHauke Mehrtens1-1/+46
The watchdog driver wants to set the watchdog timeout in ms and not in ticks, which is depending on the SoC type and the clock. Calculate the number of ticks per millisecond and provide two functions for the watchdog driver. Also return the ticks or millisecond the timer was set to in case the provided value was bigger than the max allowed value. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

2010-06-04ssb: Handle alternate SSPROM locationLarry Finger1-0/+1
In kernel Bugzilla #15825 (2 users), in a wireless mailing list thread (http://lists.infradead.org/pipermail/b43-dev/2010-May/000124.html), and on a netbook owned by John Linville (http://marc.info/?l=linux-wireless&m=127230751408818&w=4), there are reports of ssb failing to detect an SPROM at the normal location. After studying the MMIO trace dump for the Broadcom wl driver, it was determined that the affected boxes had a relocated SPROM. This patch fixes all systems that have reported this problem.

2010-04-26ssb: do not read SPROM if it does not existJohn W. Linville1-0/+2
Attempting to read registers that don't exist on the SSB bus can cause hangs on some boxes. At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.
