Subject: [PATCH] arm: dma: check clk_get() result
Date: Fri, 26 Nov 2010 20:05:55 +0300 [thread overview]
Message-ID: <1290791157-21096-1-git-send-email-segoon@openwall.com> (raw)
clk_get() may return ERR_PTR(), if so propagate return code as
imx_dma_init() return code.
Signed-off-by: Vasiliy Kulikov <segoon@openwall.com>

Cannot compile this driver, so it is not tested at all.
