spi: davinci: fix spurious i/o error davinci_spi_bufs() uses wait_for_completion_interruptible() without bothering to handle -ERESTARTSYS. Due to this, sometime, it returns prematurely when a signal is received. Since the return value is never checked, userspace eventually receives a spurious -EIO. To fix this, use un-interruptible wait_for_completion_timeout(). Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
