Subject: usb: bdc: remove duplicated error message
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a73abc28ce67989ebf881f33961d9dec9c7522b9;p=linux.git

usb: bdc: remove duplicated error message

in case devm_platform_ioremap_resource() fails, that function already
prints a relevant error message which renders the driver's dev_err()
redundant. Let's remove the unnecessary message and, while at that,
also make sure to pass along the error value returned by
devm_platform_ioremap_resource() instead of always returning -ENOMEM.
