From 1e9a47b62f7daf5a94fdd74a94dd4e076f44909a Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 26 May 2005 05:55:55 -0700 Subject: [PATCH 1/4] [PATCH] USB: sl811-hcd fixes Various fixes to the sl811-hcd driver: * Fix small glitches that crept in during recent evolution of usbcore's hcd glue layer, coupling endpoint state records to usbcore and active urbs. (As noted by folk whose boards weren't stuck on 2.6.9 kernels...) * Cope with various system-specific issues: - Some configurations (e.g. a CF-card uses this chip) have iospace addresses for the two registers, rather than memory mapped ones. - Some configurations do interesting things with IRQs; maybe the line is shared, or it doesn't support level triggering. - Not all boards can drive the chip reset line in software. * Address a potential race during unlinking. * Tweak probe/remove section info to handle the case where this segment of a platform bus is hotpluggable (e.g. CF card). (The basic problem is that CONFIG_HOTPLUG is global, which is wrong since not all busses can hotplug even on hotplug-friendly systems...) Also export the driver, so that the CF driver can depend on it. Also removed some annoying end-of-line whitespace.
