Subject: mtd: plat_nand: remove redundant return value check of platform_get_resource()
X-Git-Tag: firefly_0821_release~176^2~4541^2~8
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=840f53c31224d687a7c4a24ea118fa3c737407b0;p=firefly-linux-kernel-4.4.55.git

mtd: plat_nand: remove redundant return value check of platform_get_resource()

Remove unneeded error handling on the result of a call
to platform_get_resource() when the value is passed to
devm_ioremap_resource(). And move those two call together
to make the connection between them more clear.
