From: Ezequiel Garcia Date: Thu, 22 May 2014 23:07:02 +0000 (-0300) Subject: net: mvmdio: Use devm_* API to simplify the code X-Git-Tag: v4.14-rc1~7383^2~149^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=56ecd2cc3810b76fc88d39369d23791fbd9adf81;p=platform%2Fkernel%2Flinux-rpi.git net: mvmdio: Use devm_* API to simplify the code This commit makes use of devm_kmalloc_array() for memory allocation and the recently introduced devm_mdiobus_alloc() API to simplify driver's code. While here, remove a redundant out of memory error message. Acked-by: Sebastian Hesselbarth Signed-off-by: Ezequiel Garcia Signed-off-by: David S.
