Subject: [PATCH] fbdev: i810: include i810_main.h in i810_dvt.c
Date: Tue, 16 May 2023 22:28:09 +0200	[thread overview]
Message-ID: <20230516202814.561262-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

Building with W=1 shows that a header needs to be included to
make the prototypes visible:

drivers/video/fbdev/i810/i810_dvt.c:194:6: error: no previous prototype for 'round_off_xres' [-Werror=missing-prototypes]
drivers/video/fbdev/i810/i810_dvt.c:233:6: error: no previous prototype for 'i810fb_encode_registers' [-Werror=missing-prototypes]
drivers/video/fbdev/i810/i810_dvt.c:245:6: error: no previous prototype for 'i810fb_fill_var_timings' [-Werror=missing-prototypes]
drivers/video/fbdev/i810/i810_dvt.c:279:5: error: no previous prototype for 'i810_get_watermark' [-Werror=missing-prototypes]

Adding the header leads to another warning from a mismatched
prototype, so fix this as well:

drivers/video/fbdev/i810/i810_dvt.c:280:5: error: conflicting types for 'i810_get_watermark'; have 'u32(struct fb_var_screeninfo *,
