2020-07-16treewide: Remove uninitialized_var() usageKees Cook2-2/+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.

2020-05-31mtd: rawnand: Add an invalid ECC mode to discriminate with valid onesMiquel Raynal1-1/+1
NAND ECC modes (or providers) have their own enumeration but, unlike their algorithms counterpart, there is no invalid or uninitialized value to discriminate between an error and having chosen a no-ECC situation. Add an "invalid" entry for this purpose.

2020-05-31mtd: rawnand: Drop OOB_FIRST placement schemeMiquel Raynal2-109/+98
This scheme has been introduced for the Davinci controller and means that the OOB area must be read *before* the rest of the data. This has nothing to do with the ECC in OOB placement as it could be understood and most importantly, there is no point in having this function out of the Davinci NAND controller driver. A DT property for this scheme has been added but never used, even by the Davinci driver which only uses this scheme to change the default nand_read_page(). Move the main read_page() helper into the Davinci driver and remove the remaining boilerplate.

This helper is not very useful and very often people get confused: they use nand_release() instead of nand_cleanup(). Let's stop using nand_release() by calling mtd_device_unregister() and nand_cleanup() directly.

2020-05-31mtd: rawnand: tmio: Fix the probe error pathMiquel Raynal1-1/+1
nand_release() is supposed be called after MTD device registration. Here, only nand_scan() happened, so use nand_cleanup() instead. There is no real Fixes tag applying here as the use of nand_release() in this driver predates by far the introduction of nand_cleanup() in commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources") which makes this change possible. However, pointing this commit as the culprit for backporting purposes makes sense even if this commit is not introducing any bug.
