pcmcia: remove long deprecated pcmcia_request_exclusive_irq() function
This function was created as a deprecated fallback case back in 2010 by commit eb14120f743d ("pcmcia: re-work pcmcia_request_irq()") for legacy cases. Actual in-kernel users haven't been around for a long while. The last in-kernel user was apparently removed four years ago by commit 5f5316fcd08e ("am2150: Update nmclan_cs.c to use update PCMCIA API"). Just remove it entirely. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

@@ -46,9 +46,6 @@ This file details changes in 2.6 which affect PCMCIA card driver authors:
- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
clean up automatically on calls to pcmcia_disable_device() or
device ejection.
- - drivers still not capable of IRQF_SHARED (or not telling us so) may
- use the deprecated pcmcia_request_exclusive_irq() for the time
- being; they might receive a shared IRQ nonetheless.
* no cs_error / CS_CHECK / CONFIG_PCMCIA_DEBUG (as of 2.6.33)
