Once DCP is detected, ext_chg_active is set to true and DCP uevent reached to user space. The hvdcp main thread mark dcp_connected to true and wakesup the detector thread to do hvdcp detection. But before the detector thread gets a chance to run, DCP is removed. The disconnect uevent reached the user space and the hvdcp main thread marks the dcp_connected to false and it will not call any ioctl call. As ext_chg_active is still set to true, it is waiting for 3 seconds while processing usb disconnect. Also it is possible that DCP uevent is reached to the user space much before ext_chg_active flag is set to true in otg state machine work which later leads to timeout of 3 seconds later while processing usb disconnect. Fix these issues by maintaining different states for ext_chg_active. Upon DCP disconnect, if the ext_chg_active value is still default, mark it to inactive. This avoid the 3 seconds wait timeout while processing the usb disconnect. CRs-Fixed: 671181 Change-Id: Ic4aa6745e994a007bd6bd2e75d4f44fb8f7ac9c1 Signed-off-by: Saket Saurabh <ssaurabh@codeaurora.org>
