Message-Id: <20180104103215.15591-1-arnd@arndb.de>
Date: Thu, 4 Jan 2018 11:31:30 +0100
From: Arnd Bergmann <arnd@...db.de>

Subject: [PATCH 1/3] 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")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
