gpio: ljca: Fix duplicated IRQ mapping
[ Upstream commit 4c4e6ea4a120cc5ab58e437c6ba123cbfc357d45 ]
The generic_handle_domain_irq() function resolves the hardware IRQ
internally. The driver performed a duplicative mapping by calling
irq_find_mapping() first, which could lead to an RCU stall.
Delete the redundant irq_find_mapping() call and pass the hardware IRQ
directly to generic_handle_domain_irq().
Fixes: c5a4b6fd31e8 ("gpio: Add support for Intel LJCA USB GPIO driver")
