Subject: [PATCH v1 2/2] ACPI: platform: Move SMB0001 HID to the header and reuse
Date:   Tue, 20 Jun 2023 19:35:34 +0300
Message-Id: <20230620163534.1042-2-andriy.shevchenko@linux.intel.com>

There are at least two places in the kernel that are using
the SMB0001 HID. Make it to be available via acpi_drivers.h
header file. While at it, replace hard coded one with a
definition.
