Subject: Input: pixcir_i2c_ts - allow using with GPIO expanders
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=127520caebd9ae1b77c7026bf538a81b8fcd19a8;p=openwrt%2Fstaging%2Fblogic.git

Input: pixcir_i2c_ts - allow using with GPIO expanders

We are using threaded interrupt handler and thus are allowed to sleep.
Let's switch over to gpiod_get_value_cansleep() so that we do not get
ugly warnings in case GPIO controller might sleep when accessing GPIO.
