Date: Mon, 2 Feb 2015 12:49:04 +0530 From: Jassi Brar <jaswinder.singh@...aro.org> To: linux-kernel@...r.kernel.org Cc: Jassi Brar <jassisinghbrar@...il.com> Subject: [PATCH 1/2] mailbox: check for bit set before polling From: Jassi Brar <jassisinghbrar@...il.com> Before polling we just need to see if the TXDONE_BY_POLL bit is set in txdone_method. There may be another bit (method) specified as well, like TXDONE_BY_ACK.
