From: Lyude Date: Wed, 22 Feb 2017 21:34:53 +0000 (-0500) Subject: drm/radeon/dp_auxch: Ratelimit aux transfer debug messages X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=92c177b7947d9c889ea7b024871445015ea74221;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/radeon/dp_auxch: Ratelimit aux transfer debug messages Aux transfers always fail with non-zero status flags when there's nothing connected on the port, so we don't usually need to see all of the debugging information from it. Also, we try reprobing a -lot-, so without ratelimiting most of the kernel log is filled up with messages from radeon_dp_aux_transfer_native.
