[PATCH 5.16 0403/1039] spi: qcom: geni: handle timeout for gpi mode

[Greg Kroah-Hartman]

From: Vinod Koul <vkoul@xxxxxxxxxx>

[ Upstream commit f8039ea55d4ccac2238a247a574f0acb3bc1dc4b ]

We missed adding handle_err for gpi mode, so add a new function
spi_geni_handle_err() which would call handle_fifo_timeout() or newly
added handle_gpi_timeout() based on mode

Fixes: b59c122484ec ("spi: spi-geni-qcom: Add support for GPI dma")
