[PATCH] idetape gcc 4.1 warning fix
In both the read and write cases it will return an error if copy_{from/to}_user faults. However, I let the driver try to read/write as much as it can just as it normally would , then finally it returns an error if there was one. This was the most straight forward way to handle the error , since there isn't a clear way to clean up the buffers on error . I moved retval in idetape_chrdev_write() down into the actual code blocks since it's really once used there, and it conflicted with my ret variable. Fixes the following warning, drivers/ide/ide-tape.c: In function ‘idetape_copy_stage_from_user’: drivers/ide/ide-tape.c:2662: warning: ignoring return value of ‘copy_from_user’, declared with attribute warn_unused_result drivers/ide/ide-tape.c: In function ‘idetape_copy_stage_to_user’: drivers/ide/ide-tape.c:2689: warning: ignoring return value of ‘copy_to_user’, declared with attribute warn_unused_result Signed-off-by: Daniel Walker <dwalker@mvista.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Bartlomiej Zolnierkiewicz <B.Zolnierkiewicz@elka.pw.edu.pl> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
