Subject[PATCH] iwlagn: fix *_UCODE_API_MAX output in the firmware field
Date
Currently (3.0-rc2), modinfo iwlagn shows:
firmware: iwlwifi-5150-IWL5150_UCODE_API_MAX.ucode
firmware: iwlwifi-5000-IWL5000_UCODE_API_MAX.ucode
firmware: iwlwifi-6000g2b-IWL6000G2_UCODE_API_MAX.ucode
firmware: iwlwifi-6000g2a-IWL6000G2_UCODE_API_MAX.ucode
firmware: iwlwifi-6050-IWL6050_UCODE_API_MAX.ucode
firmware: iwlwifi-6000-IWL6000_UCODE_API_MAX.ucode
firmware: iwlwifi-100-IWL100_UCODE_API_MAX.ucode
firmware: iwlwifi-1000-IWL1000_UCODE_API_MAX.ucode
firmware: iwlwifi-105-IWL105_UCODE_API_MAX.ucode
firmware: iwlwifi-2030-IWL2030_UCODE_API_MAX.ucode
firmware: iwlwifi-2000-IWL2000_UCODE_API_MAX.ucode

which is obviously wrong, the user should not see the *_UCODE_API_MAX
macros but the actual ucode API versions here.

The problem are the
#define *_MODULE_FIRMWARE(api) *_FW_PRE #api ".ucode"
which do not expand api correctly (because this is a macro itself).

Fixed by using __stringify() from linux/stringify.h.

Further information about macro stringification can be found here:
