From: Uwe Kleine-König Date: Fri, 12 Nov 2010 10:10:55 +0000 (+0100) Subject: ARM: mx3: dynamically register mxc-mmc devices X-Git-Tag: v2.6.38-rc1~38^2~3^2~88^2~7 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6a697e3d310d79ea0e385975c57084ce22b04b36;p=karo-tx-linux.git ARM: mx3: dynamically register mxc-mmc devices Compared to the static devices the dynamic have a DMA resource. This should be save as it seems unused in the driver.
