When building with Clang + -Wtautological-pointer-compare: drivers/net/wireless/realtek/rtlwifi/regd.c:389:33: warning: comparison of address of 'rtlpriv->regd' equal to a null pointer is always false [-Wtautological-pointer-compare] if (wiphy == NULL || &rtlpriv->regd == NULL) ~~~~~~~~~^~~~ ~~~~ 1 warning generated. The address of an array member is never NULL unless it is the first struct member so remove the unnecessary check. This was addressed in the staging version of the driver in commit f986978b ("Staging: rtlwifi: remove unnecessary NULL check"). While we are here, fix the following checkpatch warning: CHECK: Comparison to NULL could be written "!wiphy" 35: FILE: drivers/net/wireless/realtek/rtlwifi/regd.c:389: + if (wiphy == NULL) Fixes: 0c817338 ("rtl8192ce: Add new driver") Link:https://github.com/ClangBuiltLinux/linux/issues/750 Signed-off-by:Nathan Chancellor <natechancellor@gmail.com> Acked-by:
