Subject: Re: [PATCH v2 4/4] drm/bridge: ti-sn65dsi86: Check the regmap return value when setting a GPIO

Quoting Douglas Anderson (2020-06-12 12:30:50)
> The ti_sn_bridge_gpio_set() got the return value of
> regmap_update_bits() but didn't check it.  The function can't return
> an error value, but we should at least print a warning if it didn't
> work.
> 
> This fixes a compiler warning about setting "ret" but not using it.
