[PATCH 1/2] ata: ahci (gcc13): use BIT() for bit definitions in enum

From: Jiri Slaby (SUSE)
Date: Mon Oct 31 2022 - 07:43:56 EST

gcc13 now uses the type of the enum for all its members [1]. Given the
ata enum defines its members using both unsigned and signed ints, the
type of the enum is promoted to long.

Make sure most the members are unsigned ints using the BIT() macro. The
rest will be converted separately in the next patch.

The error in question is for example this:
drivers/block/mtip32xx/mtip32xx.c:722:25: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'long in'
