From: Mark Brown Date: Wed, 16 Mar 2011 18:18:53 +0000 (+0000) Subject: ASoC: Remove bogus check for register validity in debugfs write X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b1a56b331aec59be04f25ac99694d855d591c539;p=openwrt%2Fstaging%2Fblogic.git ASoC: Remove bogus check for register validity in debugfs write Since not all registers need to be cached and the cache is entirely optional anyway we shouldn't be checking that a register is in the cached range. If the register is invalid then the actual I/O code can determine that and report an error. Similarly, the step size can and should be enforced by the lower level code if it's important.
