From: Mauro Carvalho Chehab Date: Sun, 28 Apr 2013 10:15:41 +0000 (-0300) Subject: [media] cx88: make core less verbose X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=02615ed5e1b2283db2495af3cf8f4ee172c77d80;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git [media] cx88: make core less verbose Along the time, several debug messages were added at cx88-cards. While those are still useful to track some troubles with tuners, they're too verbose: [ 5768.281801] cx88[0]: Calling XC2028/3028 callback [ 5768.287388] cx88[0]: Calling XC2028/3028 callback [ 5768.292575] cx88[0]: Calling XC2028/3028 callback [ 5768.299408] cx88[0]: Calling XC2028/3028 callback [ 5768.306244] cx88[0]: Calling XC2028/3028 callback ... and, most of the time, useless. So, disable them, except if core_debug modprobe parameter is used.
