Clang static checker (scan-build) has some warnings as follows. included from drivers/net/wireless/broadcom/brcm80211/brcmfmac/common.c:16 drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil.h:123:2: warning:Assigned value is garbage or undefined [core.uninitialized.Assign] 123 | __le32 data_le = cpu_to_le32(*data); | ^~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~ drivers/net/wireless/broadcom/brcm80211/brcmfmac/common.c:138:3:warning Value stored to 'err' is never read [deadcode.DeadStores] There are some functions like brcmf_fil_{cmd,iovar,basscfg}_int_get() which read the value of its parameter, but some callers have not initialized these parameters which will be read. And this patchset fixes these problems. BTW, maybe merge this patchset into one patch is more better because the num of changed code is small. I split it into multiple patches because of these different 'Fixes' tags.
