* treewide: Remove uninitialized_var() usageKees Cook2020-07-161-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* video: fbdev: riva: deprecate pci_get_bus_and_slot()Sinan Kaya2018-01-171-7/+13
| | | | | | | | | | | | | | | | | | | | pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function in favor of pci_get_domain_bus_and_slot(). struct riva_par has a pointer to struct pci_dev. Use the pci_dev member to extract the domain information. Change the function signature for CalcStateExt and RivaGetConfig to pass in struct pci_dev in addition to RIVA_HW_INST so that code inside the riva_hw.c can also calculate domain number and pass it to pci_get_domain_bus_and_slot().

* video: move fbdev to drivers/video/fbdevTomi Valkeinen2014-04-171-0/+2268
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
