From 95e57ab2cbd8b016327b23d76da8a96cbd26ac0c Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sat, 26 Apr 2008 01:02:22 -0300 Subject: ACPI: thinkpad-acpi: claim tpacpi as an official short handle (v1.1) Unfortunately, a lot of stuff in the kernel has size limitations, so "thinkpad-acpi" ends up eating up too much real estate. We were using "tpacpi" in symbols already, but this shorthand was not visible to userland. Document that the driver will use tpacpi as a short hand where necessary, and use it to name the kernel thread for NVRAM polling (now named "ktpacpi_nvramd"). Also, register a module alias with the shorthand. One can refer to the module using the shorthand name.
