Re: [PATCH v2 26/30] misc: eeprom: at24: Tell the compiler that ACPI functions may not be used

From: Lee Jones
Date: Wed Jul 01 2020 - 05:36:28 EST


... as is the case when !CONFIG_ACPI.

Fixes the following W=1 kernel build warning:

drivers/misc/eeprom/at24.c:228:36: warning: âat24_acpi_idsâ defined but not used [-Wunused-const-variable=]

- Resending to add the I2C ML and Bartosz to the conversation
- Looks like I missed them when running get_maintainer.pl
- This patch, like all the others in the set, should go in via Misc
- Although the patches are orthogonal, this makes life easier for Greg
