Subject: UBIFS: fix sparse warnings
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6a4a9b438fe43397f4652853838f284cddd629b5;p=linux-beck.git

UBIFS: fix sparse warnings

fs/ubifs/compress.c:111:8: warning: incorrect type in argument 5 (different signedness)
fs/ubifs/compress.c:111:8:    expected unsigned int *dlen
fs/ubifs/compress.c:111:8:    got int *out_len
fs/ubifs/compress.c:175:10: warning: incorrect type in argument 5 (different signedness)
fs/ubifs/compress.c:175:10:    expected unsigned int *dlen
fs/ubifs/compress.c:175:10:    got int *out_len

Fix this by adding a cast to (unsigned int *). We guarantee that
our lengths are small and no overflow is possible.
