Subject: video: wm8505fb: Convert to devm_ioremap_resource()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8e524c95040aa521283aba126c047381eadaed39;p=linux-beck.git

video: wm8505fb: Convert to devm_ioremap_resource()

Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.
