Subject: mtd: rawnand: sunxi: Convert to common field_{get,prep}() helpers
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ec64aa7fef37c84507eab43fa29985a17db85ed;p=thirdparty%2Fkernel%2Flinux.git

mtd: rawnand: sunxi: Convert to common field_{get,prep}() helpers

Drop the driver-specific field_get() and field_prep() macros, in favor
of the globally available variants from <linux/bitfield.h>.
