From: Artem Bityutskiy Date: Mon, 27 Aug 2012 14:14:58 +0000 (+0300) Subject: UBI: print less X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=719bb84017fcfc949a77e150dd5b045e90a4ebc9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git UBI: print less UBI currently prints a lot of information when it mounts a volume, which bothers some people. Make it less chatty - print only important information by default. Get rid of 'dbg_msg()' macro completely.
