Subject: gpio/omap: fix missing dataout context save in _set_gpio_dataout_reg
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2c836f7ea5e7b5eec2a798e02b1d76ea791fa094;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

gpio/omap: fix missing dataout context save in _set_gpio_dataout_reg

There are two functions, _set_gpio_dataout_reg() and _set_gpio_dataout_mask()
which writes to dataout register and the dataout context must be saved.
It is missing in the first function, _set_gpio_dataout_reg(). Fix this.
