ide: ide-cd_ioctl.c fix sparse integer as NULL pointer warnings
The function ide_cd_queue_pc should be checked as the bufflen arg is dereferenced and lots of callers are passing in NULL. drivers/ide/ide-cd_ioctl.c:124:46: warning: Using plain integer as NULL pointer drivers/ide/ide-cd_ioctl.c:149:47: warning: Using plain integer as NULL pointer drivers/ide/ide-cd_ioctl.c:231:46: warning: Using plain integer as NULL pointer drivers/ide/ide-cd_ioctl.c:374:46: warning: Using plain integer as NULL pointer Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
