Subject: [PATCH] Staging: rts5208: Remove unused functions
Date: Sat, 26 Mar 2016 12:42:43 +0530 [thread overview]
Message-ID: <1458976363-21142-1-git-send-email-bhumirks@gmail.com> (raw)
The functions rtsx_disable_card_int, rtsx_undo_delink,
rtsx_check_link_ready are not used anywhere in the kernel. So,remove
their definition and prototype.
