From 959eea2191e8d74b16ef019b0f4bf875c14f4547 Mon Sep 17 00:00:00 2001 From: Olav Kongas Date: Thu, 3 Nov 2005 17:38:14 +0200 Subject: [PATCH] USB: isp116x-hcd: cleanup The attached patch makes a cleanup of isp116x-hcd. Most of the volume of the patch comes from 2 sources: moving the code around to get rid of a few function prototypes and reworking register dumping functions/macros. Among other things, switched over from using procfs to debugfs. Cleanup. The following changes were made: - Rework register dumping code so it can be used for dumping to both syslog and debugfs. - Switch from procfs to debugfs.. - Die gracefully on Unrecoverable Error interrupt. - Fix memory leak in isp116x_urb_enqueue(), if HC happens to die in a narrow time window. - Fix a 'sparce' warning (unnecessary cast). - Report Devices Removable for root hub ports by default (was Devices Permanently Attached). - Move bus suspend/resume functions down in code to get rid of a few function prototypes. - A number of one-line cleanups. - Add an entry to MAINTAINERS.
