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':

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.
