[media] rc: img-ir: fix error in parameters passed to irq_free()
[ Upstream commit 80ccf4ad06dc9d2f06a8347b2d309cdc959f72b3 ]
img_ir_remove() passes a pointer to the ISR function as the 2nd
parameter to irq_free() instead of a pointer to the device data
structure.
This issue causes unloading img-ir module to fail with the below
warning after building and loading img-ir as a module.
