From: Laurent Pinchart Date: Thu, 20 Mar 2014 14:00:31 +0000 (+0100) Subject: sh_eth: Use the platform device for memory allocation X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aa8d422510969b705656e49fc0166d862aca9246;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git sh_eth: Use the platform device for memory allocation Memory allocated for the MDIO bus with the devm_kzalloc() API is associated with the network device. While this will cause memory to be freed at the right time, it doesn't allow allocating memory before the network device is initialized. Replace the network device with the parent platform device for memory allocation to remove that dependency. This also improves consistency with the other devm_* calls in the driver that all use the platform device. Signed-off-by: Laurent Pinchart Acked-by: Geert Uytterhoeven Signed-off-by: David S.
