Waiting for M_CMD_ABORT_EN in geni_i2c_abort_xfer() races with the interrupt handler which will read and clear the abort bit, the result is that every abort attempt takes 1 second and is followed by a message about the abort having times out. Introduce a new state variable to carry the abort_done state from the interrupt handler back to geni_i2c_abort_xfer(). Also, turn NACK and TIMEOUT errors into debug messages Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Reviewed-by: Vinod Koul <vkoul@kernel.org> [wsa: squashed two patches into one] Signed-off-by: Wolfram Sang <wsa@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
