From 6b448af46e2a2fc9563fd86fb3b7cf06fcf2dd47 Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Tue, 16 Dec 2014 11:51:44 +0100 Subject: [PATCH] drivers: usb: dwc2: remove 'force' parameter from kill_all_requests() This patch fixes in simpler way the bug described in [1] and [2]. It looks like DWC2 is the only UDC driver that doesn't force usb requests to complete in ep_disable() function. This causes described problem, because we have no guarantee that all requests will be completed before unbind of usb function. To fix this problem we force all requests of disabled endpoint to complete. Also currently running request is not handled. This allowed to simplify code of kill_all_requests() function, because 'force' parameter is always set to true, so we don't need it anymore. In s3c_hsotg_rx_data() we change function used to print message when active request is NULL from dev_warn() to dev_dbg(), because such situation is harmless for driver and now it can take place during normal endpoint disabling.
