Subject: [PATCH] iwlwifi: fix false-positive maybe-uninitialized warning
Date: Mon, 10 Dec 2018 21:39:06 +0100	[thread overview]
Message-ID: <20181210203945.2147135-1-arnd@arndb.de> (raw)

With CONFIG_NO_AUTO_INLINE, we run into a silly warning when
gcc fails to remember that n_profiles is constant across
the function call to iwl_mvm_sar_set_profile:

drivers/net/wireless/intel/iwlwifi/mvm/fw.c: In function 'iwl_mvm_sar_get_ewrd_table':
drivers/net/wireless/intel/iwlwifi/mvm/fw.c:746:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Marking that function 'inline' avoids the warning.
