Subject: [PATCH] spi: tegra114: clear packed bit for unpacked mode
Git-commit: 7b3d10cdf54b8bc1dc0da21faed9789ac4da3684
Patch-mainline: v5.2-rc1
References: bsc#1051510
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.
