Subject: [PATCH v6 0/5] usb: usbtmc: Add support for missing functions in
 USBTMC-USB488 spec

Implement support for the USB488 defined READ_STATUS_BYTE ioctl (1/5)
and SRQ notifications with fasync (2/5) and poll/select (3/5) in order
to be able to synchronize with variable duration instrument
operations.

Add ioctls for other USB488 requests: REN_CONTROL, GOTO_LOCAL and
LOCAL_LOCKOUT. (4/5)

Add convenience ioctl to return all device capabilities (5/5)

 PATCH Changelog:
    v6 - Remove more excess newlines
         Rearrange declaration blocks aesthetically
	 Remove __func__ parameter from dev_xxx calls
	 Simplify tests for interrupt-in notifications
	 Propagate return code from usb_submit_urb()
	 
    v5 - Remove excess newlines and parens
       - Move dev variable initialisations to declaration
       - Add comment on interrupt btag wrap
       - simplify test in usbtmc_free_int()
       
    v4 - Remove excess newlines and parens
       - simplify some expressions

    v3 - Split into multiple patches as per gregkh request

    V2 - Fix V1 bug: not waking sleepers on disconnect.

    V1 - Original patch

 Testing:
    All functions tested ok on an USBTMC-USB488 compliant oscilloscope
