Subject: drm/nouveau/dp: convert to use ERR_CAST()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=01738c4f4725005b8a8cdf0205761cb24b192a23;p=thirdparty%2Fkernel%2Flinux.git

drm/nouveau/dp: convert to use ERR_CAST()

As opposed to open-code, use ERR_CAST to clearly indicate that this is a
pointer to an error value and a type conversion is performed.
