Subject: media: dvb: fix DVB_MMAP symbol name
X-Git-Tag: v4.16-rc4~9^2~9
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=ec5b100462543aee1f3e139e168699fd3b05cdc6;p=linux.git

media: dvb: fix DVB_MMAP symbol name

CONFIG_DVB_MMAP was misspelled either as CONFIG_DVB_MMSP
or DVB_MMAP, so it had no effect at all. This fixes that,
to make it possible to build it again.

Fixes: 4021053ed52d ("media: dvb-core: make DVB mmap API optional")
