[PATCH net] ipw2x00: use DEVICE_ATTR_*() macro

From: Meng Tang
Date: Wed Apr 06 2022 - 09:05:07 EST

Next message: Kai Huang: "Re: [RFC PATCH v5 023/104] x86/cpu: Add helper functions to allocate/free MKTME keyid"
Previous message: Randy Dunlap: "[PATCH v2] keys: remove __user annotation from function prototype"
Next in thread: Kalle Valo: "Re: [PATCH net] ipw2x00: use DEVICE_ATTR_*() macro"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Use DEVICE_ATTR_*() helper instead of plain DEVICE_ATTR,
which makes the code a bit shorter and easier to read.
