Subject: [ 053/128] serial:ifx6x60:Delete SPI timer when shut down port

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: chao bi <chao.bi@...el.com>

commit 014b9b4ce84281ccb3d723c792bed19815f3571a upstream.

When shut down SPI port, it's possible that MRDY has been asserted and a SPI
timer was activated waiting for SRDY assert, in the case, it needs to delete
this timer.
