[patch] sony-laptop: leak in error handling sony_nc_lid_resume_setup()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We need to decrement "i" first because the current "i" was not allocated
succesfully.  Also we should go free the way down to zero to avoid a
leak.
