Subject: ACPI: AC: Define ACPI_AC_CLASS in one place
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=236ad358166cca167e6ed33639bb7948e7a2f6fd;p=thirdparty%2Flinux.git

ACPI: AC: Define ACPI_AC_CLASS in one place

The ACPI_AC_CLASS symbol is defined in several places in the same way
which is rather unfortunate.

Instead, define it in one common header file (acpi_bus.h) so that it is
accessible to all of its users.

No intentional functional impact.
