Subject: ide: remove duplicated assignment to 'cursg'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8b76f5da49f0d432a747dbc0c4667dcd1ffb9945;p=linux.git

ide: remove duplicated assignment to 'cursg'

Pointer cursg is initialized to cmd->cursg and again re-assigned the
same value a few lines later, hence the second assignment is redundant
and can be removed.

Cleans up clang warning:
drivers/ide/ide-taskfile.c:229:22: warning: Value stored to 'cursg'
during its initialization is never read
