From 73a94d86a8625371f76de0ee12dc5bacd3ed42c0 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sat, 4 Apr 2009 04:25:47 +0000 Subject: thinkpad-acpi: add new debug helpers and warn of deprecated atts Add a debug helper that discloses the TGID of the userspace task attempting to access the driver. This is highly useful when dealing with bug reports, since often the user has no idea that some userspace application is accessing thinkpad-acpi... Also add a helper to log warnings about sysfs attributes that are deprecated. Use the new helpers to issue deprecation warnings for bluetooth_enable and wwan_enabled, that have been deprecated for a while, now.
