2020-11-10hil/parisc: Disable HIL driver when it gets stuckHelge Deller
commit 879bc2d27904354b98ca295b6168718e045c4aa2 upstream. When starting a HP machine with HIL driver but without an HIL keyboard or HIL mouse attached, it may happen that data written to the HIL loop gets stuck (e.g. because the transaction queue is full). Usually one will then have to reboot the machine because all you see is and endless output of: Transaction add failed: transaction already queued? In the higher layers hp_sdc_enqueue_transaction() is called to queued up a HIL packet. This function returns an error code, and this patch adds the necessary checks for this return code and disables the HIL driver if further packets can't be sent. Tested on a HP 730 and a HP 715/64 machine. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Update drivers to new input layer changes. Signed-off-by: Helge Deller <deller@parisc-linux.org> Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Reorder code in gscps2_interrupt() and only enable ports when opened. This fixes issues with hangs booting an SMP kernel on my C360. Previously serio_interrupt() could be called before the lock in struct serio was initialised.
