Subject: drivers/memstick/core/mspro_block: use kmemdup
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=de6cdcb5ce504c9d346858569e4ad2ca3ac2fe45;p=deliverable%2Flinux.git

drivers/memstick/core/mspro_block: use kmemdup

Use kmemdup when some other buffer is immediately copied into allocated
region.  It replaces call to allocation followed by memcpy, by a single
call to kmemdup.

[akpm@linux-foundation.org: remove unneeded cast to void*]
