Subject: [PATCH] fbdev/wm8505fb: select CONFIG_FB_IOMEM_FOPS
Date: Fri, 18 Oct 2024 15:12:49 +0000 [thread overview]
Message-ID: <20241018151258.3574617-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The fb_io_mmap() function is used in the file operations but
not enabled in all configurations unless FB_IOMEM_FOPS gets
selected:
ld.lld-20: error: undefined symbol: fb_io_mmap
>>> referenced by wm8505fb.c
>>> drivers/video/fbdev/wm8505fb.o:(wm8505fb_ops) in archive vmlinux.a
Fixes: 11754a504608 ("fbdev/wm8505fb: Initialize fb_ops to fbdev I/O-memory helpers")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
