From: Sam Bobroff Date: Fri, 16 Aug 2019 04:48:13 +0000 (+1000) Subject: powerpc/eeh: Convert log messages to eeh_edev_* macros X-Git-Tag: v5.15~5474^2~177 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ff8f36fc770dd2b3eb294312f270db8cf94cc13;p=platform%2Fkernel%2Flinux-starfive.git powerpc/eeh: Convert log messages to eeh_edev_* macros Convert existing messages, where appropriate, to use the eeh_edev_* logging macros. The only effect should be minor adjustments to the log messages, apart from: - A new message in pseries_eeh_probe() "Probing device" to match the powernv case. - The "Probing device" message in pnv_eeh_probe() is now generated slightly later, which will mean that it is no longer emitted for devices that aren't probed due to the initial checks.
