[PATCH] spi: tegra114: clear packed bit for unpacked mode

From: Sowjanya Komatineni
Date: Wed Mar 27 2019 - 01:56:23 EST


Fixes: Clear packed bit when not using packed mode.

Packed bit is not cleared when not using packed mode. This results
in transfer timeouts for the unpacked mode transfers followed by the
packed mode transfers.
