Subject: fs/fat/fat_write: Merge calls to set_cluster()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1d7f2ece69c9d80264321bc4ee07f57eec392538;p=u-boot.git

fs/fat/fat_write: Merge calls to set_cluster()

set_contents() had uselessly split calls to set_cluster(). Merge these
calls, which removes some cases of set_cluster() being called with a
size of zero.
