gpio: mvebu: fix blink counter register selection
The blink counter A was always selected because 0 was forced in the blink select counter register. The variable 'set' was obviously there to be used as the register value, selecting the B counter when id==1 and A counter when id==0. Tested on clearfog-pro (Marvell 88F6828) Fixes: 757642f9a584 ("gpio: mvebu: Add limited PWM support") Reviewed-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Reviewed-by: Ralph Sennhauser <ralph.sennhauser@gmail.com> Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
