[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 âidetape_copy_stage_from_userâ:
drivers/ide/ide-tape.c:2662: warning: ignoring return value of âcopy_from_userâ, declared with attribute warn_unused_result
drivers/ide/ide-tape.c: In function âidetape_copy_stage_to_userâ:
drivers/ide/ide-tape.c:2689: warning: ignoring return value of âcopy_to_userâ, declared with attribute warn_unused_result
