[ Upstream commit9373771aae] Quieten a gcc (11.3.0) build error or warning by checking the function call status and returning -EBUSY if the function call failed. This is similar to what several other wireless drivers do for the SIOCGIWRATE ioctl call when there is a locking problem. drivers/net/wireless/cisco/airo.c: error: 'status_rid.currentXmitRate' is used uninitialized [-Werror=uninitialized] Fixes:1da177e4c3("Linux-2.6.12-rc2") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Link: https://lore.kernel.org/r/39abf2c7-24a-f167-91da-ed4c5435d1c4@linux-m68k.org Link: https://lore.kernel.org/r/20230709133154.26206-1-rdunlap@infradead.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Sasha Levin <sashal@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.
