From 2342f3323c9a76367a1d7f9a35525ee3cb3911df Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Sat, 30 Jun 2007 16:21:52 +0200 Subject: sdio: allow for mmc_claim_host to be aborted It is sometimes necessary to give up on trying to claim the host lock, especially if that happens in a thread that has to be stopped. While at it, fix the description for mmc_claim_host() which was wrong.
