Subject: [PATCH 0/8] staging: gpib: Fixes and cleanup for gpio driver

This set of patches addresses a number of fixes and cleanups for
the gpio bitbang driver.

Patch 1 Fixes the faulty implementation of the request_system_control
        function.
Patch 2	Moves the code for setting the controller-in-charge to the
        correct function as per the standard.
Patch 3 Defers enabling the SRQ irq to when becoming system controller.
Patch 4 Removes need for cumbersome setup for the activity led with
        the yoga board.
Patch 5 Removes a no longer needed workaround for missed irqs.
Patch 6 Corrects the error return for no listeners so that the user
        library reports the appropriate user error code.
Patch 7 Improves the code for the allocate_gpios function
Patch 8 Fixes potential hangs due to undefined control line state
        on initialization.
