[PATCH] drm/st7571-i2c: select CONFIG_DRM_CLIENT_SELECTION

[Arnd Bergmann]

From: Arnd Bergmann <arnd at arndb.de>

The newly added driver calls drm_client_setup(), but that is not
always built in:

x86_64-linux-ld: vmlinux.o: in function `st7571_probe':
st7571-i2c.c:(.text+0x7b7119): undefined reference to `drm_client_setup'

Select the appropriate Kconfig symbol.

Fixes: 4b35f0f41ee2 ("drm/st7571-i2c: add support for Sitronix ST7571 LCD controller")
