Subject: gpio: ep93xx: get rid of bogus __raw* accessors
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d27e06ac5dcf60d5502269e1875bcb0f05f1b1c1;p=linux-beck.git

gpio: ep93xx: get rid of bogus __raw* accessors

I have no idea why this driver is using __raw* accessors for
reading and writing registers, I suspect it is just force of
habit or copy/paste. Change all to readb()/writeb() except
one chain where I used writeb_relaxed() up until the last
writeb().
