mwifiex_sdio_resume() intializes pm_flag, just like mwifiex_sdio_suspend(), but does not use it. Compiling with W=1 gives the following warning, fix it. mwifiex/sdio.c: In function ‘mwifiex_sdio_resume’: mwifiex/sdio.c:234:16: warning: variable ‘pm_flag’ set but not used [-Wunused-but-set-variable] sdio_get_host_pm_caps() is just an acessor, so the call to it is safe to remove. The unused variable seems to be present since 5e6e3a92b9a4 which introduced mwifiex_sdio_resume().
