[PATCH] PCI: dra7xx: Fix threaded IRQ handler registration
From: Siddharth Vadapalli
Date: Sat Aug 24 2024 - 03:22:12 EST
Commit da87d35a6e51 ("PCI: dra7xx: Use threaded IRQ handler for
"dra7xx-pcie-main" IRQ") switched from devm_request_irq() to
devm_request_threaded_irq(). In this process, the "handler" and the
"thread_fn" parameters were erroneously interchanged, with "NULL" being
passed as the "handler" and "dra7xx_pcie_irq_handler()" being registered
as the function to be called in a threaded interrupt context.
Fix this by interchanging the "handler" and "thread_fn" parameters.
While at it, correct the indentation.
