Subject: ARM: OMAP: Fix build error when mmc_omap is built as module
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d517110243130965e2803cc2373d434bdaf6dafb;p=linux-beck.git

ARM: OMAP: Fix build error when mmc_omap is built as module

Otherwise we get the following error:

arch/arm/mach-omap2/built-in.o: In function `n8x0_mmc_callback':
twl-common.c:(.text+0x108a0): undefined reference to
`omap_mmc_notify_cover_event'

Fix this by warning about unusable MMC cover events.

The long term fix needs to change the MMC drivers to
register board specific callbacks directly with PMIC.
