From: Miguel Ojeda
Date: Mon Feb 19 2018 - 11:07:35 EST


Compiling with W=1 with gcc 7.2.0 gives 2 warnings:

drivers/auxdisplay/img-ascii-lcd.c:233: warning: Function parameter or
member 't' not described in 'img_ascii_lcd_scroll'
drivers/auxdisplay/img-ascii-lcd.c:233: warning: Excess function
parameter 'arg' description in 'img_ascii_lcd_scroll'

I saw this while fixing the ones reported by the build service.
I will queue it up for 4.17.
