We got a compile warning shows below: drivers/net/wireless/marvell/mwifiex/sdio.c: In function 'mwifiex_sdio_remove': drivers/net/wireless/marvell/mwifiex/sdio.c:377:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] Per the code, it didn't check if mwifiex_sdio_read_fw_status finish successfully. We should at least check the return of mwifiex_sdio_read_fw_status, otherwise the following check of firmware_stat and adapter->mfg_mode is pointless as the device is probably dead.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
