2015-05-20mtd: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven1-1/+1
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

Previously, when probing a CFI chip which was write-protected at the hardware level, the probe would fail due to the fact it could not put the chip into QUERY mode.

2014-12-12mtd: physmap_of: fix potential NULL dereferenceArd Biesheuvel1-5/+3
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.

2014-09-22mtd: physmap_of: Add non-obsolete map_rom probeAaron Sierra1-0/+4
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).

The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.
