Subject: [media] ov2640: Propagate the real error on devm_clk_get() failure
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=877f1af154ec427d9c3c936a39a10afda95dcb97;p=openwrt%2Fstaging%2Fblogic.git

[media] ov2640: Propagate the real error on devm_clk_get() failure

devm_clk_get() may return different error codes other than -EPROBE_DEFER,
so it is better to return the real error code instead.
