mtd: physmap_of: fix potential NULL dereference

2014-12-13T03:12:16Z

On device remove, when testing the cmtd field of an of_flash struct to decide whether it is a concatenated device or not, we get a false positive on cmtd == NULL, and dereference it subsequently. This may occur if of_flash_remove() is called from the cleanup path of of_flash_probe(). Instead, test for NULL first, and only then perform the test for a concatenated device.

mtd: bfin-async-flash: Remove unused variable

2014-10-22T08:35:41Z

Avoid the following compile warning: drivers/mtd/maps/bfin-async-flash.c: In function 'bfin_flash_probe': drivers/mtd/maps/bfin-async-flash.c:129: warning: unused variable 'ret' Signed-off-by: Aaron Sierra Signed-off-by: Brian Norris

mtd: maps: drop owner assignment from platform_drivers

2014-10-20T14:20:57Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

mtd: physmap_of: Add non-obsolete map_rom probe

2014-09-22T17:13:13Z

Previously, the only way to map a NOR device as a simple ROM was to use the obsolete "direct-mapped" compatible binding (which further requires device_type = "nor" and probe-type = "NOR" properties). This patch adds an "mtd-rom" compatible binding to the "map_rom" probe type. Signed-off-by: Aaron Sierra Signed-off-by: Brian Norris

mtd: physmap_of: Fix ROM support via OF

2014-09-22T17:13:11Z

The "ROM" and unknown probe types within the obsolete "direct-mapped" probe function used the nonexistent "mtd_rom" probe instead of the intended "map_rom". Signed-off-by: Aaron Sierra Signed-off-by: Brian Norris

mtd: gpio_flash: handle case where offset + len exceeds the window size

2014-08-19T18:53:10Z

Fix the bug in handling gpio flash read/write when offset + len from MTD exceeds the window size Signed-off-by: Aaron Wu [Brian: made some commentary edits. Also note that the BUG_ON() was provably false for all non-negative inputs (since x % y <= x), so we dropped it.] Signed-off-by: Brian Norris

mtd: maps: solutionengine: drop excess dependency

2014-08-19T18:53:09Z

Already depends on SOLUTION_ENGINE, so we don't need the SUPERH dependency too. Signed-off-by: Brian Norris

mtd: use NULL instead of 0 for an address

2014-08-19T18:53:05Z

Use NULL instead of 0 when returning an address. This fixes a sparse warning. Signed-off-by: Martin Kepplinger Signed-off-by: Brian Norris
