Subject: [PATCH AUTOSEL 6.0 02/30] spi: tegra210-quad: Fix combined sequence

From: Krishna Yarlagadda <kyarlagadda@...dia.com>

[ Upstream commit 8777dd9dff4020bba66654ec92e4b0ab6367ad30 ]

Return value should be updated to zero in combined sequence routine
if transfer is completed successfully. Currently it holds timeout value
resulting in errors.
