Subject: [PATCH] iwlwifi: add missing type declaration
Date: Mon, 11 Jul 2016 22:49:53 +0200 [thread overview]
Message-ID: <20160711205020.1587254-1-arnd@arndb.de> (raw)
The iwl-debug.h header relies in implicit inclusion of linux/device.h and
we get a lot of warnings without that:
drivers/net/wireless/intel/iwlwifi/iwl-debug.h:44:23: error: 'struct device' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
void __iwl_err(struct device *dev, bool rfkill_prefix, bool only_trace,
^~~~~~
In file included from drivers/net/wireless/intel/iwlwifi/iwl-eeprom-read.h:66:0,
from drivers/net/wireless/intel/iwlwifi/iwl-eeprom-read.c:68:
drivers/net/wireless/intel/iwlwifi/iwl-trans.h: In function 'iwl_trans_tx':
drivers/net/wireless/intel/iwlwifi/iwl-trans.h:1030:348: error: passing argument 1 of '__iwl_err' from incompatible pointer type [-Werror=incompatible-pointer-types]
IWL_ERR(trans, "%s bad state = %d\n", __func__, trans->state);
^
In file included from drivers/net/wireless/intel/iwlwifi/iwl-eeprom-read.c:67:0:
drivers/net/wireless/intel/iwlwifi/iwl-debug.h:44:6: note: expected 'struct device *' but argument is of type 'struct device *'
void __iwl_err(struct device *dev, bool rfkill_prefix, bool only_trace,
^~~~~~~~~
The easiest workaround is to just declare 'struct device' before its first use,
rather than including the entire header file.
