| |
From: Arnd Bergmann <arnd@arndb.de>
A simplification of get_unaligned() clashes with callers that pass in a character pointer, causing a harmless warning like:
block/partitions/msdos.c: In function 'msdos_partition': include/asm-generic/unaligned.h:13:22: warning: 'packed' attribute ignored for field of type 'u8' {aka 'unsigned char'} [-Wattributes]
Remove the get_unaligned() call and just use the byte directly.
