Subject: [PATCH 1/5] spi: tegra210-quad: Fix combined sequence
Date: Sat, 1 Oct 2022 17:51:44 +0530	[thread overview]
Message-ID: <20221001122148.9158-1-kyarlagadda@nvidia.com> (raw)

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