Subject: ramips: aw9523: add can_sleep flag for GPIO chip
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=00b194871cd82dfbaf678626e49816ab3a51ece8;p=openwrt%2Fstaging%2Fmans0n.git

ramips: aw9523: add can_sleep flag for GPIO chip

The GPIO expander is connected via I2C, thus the can_sleep flag has to
be set to true. This should fix spurious "scheduling while atomic" bugs
in the kernel ringbuffer.
