Subject[PATCH] dmaengine: ioatdma: remove unused function missed during dma_v2 removal
Date
Commit 7f832645d0e5 ("dmaengine: ioatdma: remove ioatdma v2 registration")
missed to remove dca2_tag_map_valid() during its removal. Hence, since
then, dca2_tag_map_valid() is unused and make CC=clang W=1 warns:

drivers/dma/ioat/dca.c:44:19:
warning: unused function 'dca2_tag_map_valid' [-Wunused-function]

So, remove this unused function and get rid of a -Wused-function warning.

Signed-off-by: Lukas Bulwahn <lukas.bulwahn@gmail.com>

applies cleanly on current master and next-20201112

Maciej, please ack.

Vinod, Dan, please pick this minor non-urgent clean-up patch.

/*
* "Legacy" DCA systems do not implement the DCA register set in the
