-Subject: [PATCH] ata: ahci: fix enum constants for gcc-13
-
-gcc-13 slightly changes the type of constant expressions that are defined
-in an enum, which triggers a compile time sanity check in libata:
-
-linux/drivers/ata/libahci.c: In function 'ahci_led_store':
-linux/include/linux/compiler_types.h:357:45: error: call to '__compiletime_assert_302' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long)
-357 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
-
-The new behavior is that sizeof() returns the same value for the
-constant as it does for the enum type, which is generally more sensible
-and consistent.
-
-The problem in libata is that it contains a single enum definition for
-lots of unrelated constants, some of which are large positive (unsigned)
-integers like 0xffffffff, while others like (1<<31) are interpreted as
-negative integers, and this forces the enum type to become 64 bit wide
-even though most constants would still fit into a signed 32-bit 'int'.
-
-Fix this by changing the entire enum definition to use BIT(x) in place
-of (1<<x), which results in all values being seen as 'unsigned' and
-fitting into an unsigned 32-bit type.
