X-Git-Tag: upstream/snapshot3+hdmi~5288^2~11^2~89
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6f3ed4ec182d191d1ba48fbf5aed021d2d00dd37;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

usb: host: ehci-mv: fix PHY error handling

PHY layer no longer returns NULL. We must
switch from IS_ERR_OR_NULL() to IS_ERR().
