We get warning of using a unsigned variable being compared to less than zero. The comparison is correct as it checks for errors from previous call to qcom_swrm_get_alert_slave_dev_num(), so we should use a signed variable here. While at it, drop the superfluous initialization as well drivers/soundwire/qcom.c: qcom_swrm_irq_handler() warn: impossible condition '(devnum < 0) => (0-255 < 0)' Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Vinod Koul <vkoul@kernel.org> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Bjorn Andersson <bjorn.andersson@linaro.org> Link: https://lore.kernel.org/r/20210331155520.2987823-1-vkoul@kernel.org Signed-off-by: Vinod Koul <vkoul@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.
