[PATCH 0/5] serial: Remove redundant error messages on IRQ request failure

Commit 55b48e23f5c4 ("genirq/devres: Add error handling in
devm_request_*_irq()") added automatic error logging to
devm_request_threaded_irq() and devm_request_any_context_irq()
via the new devm_request_result() helper, which prints device
name, IRQ number, handler functions, and error code on failure.

Since devm_request_irq() is a static inline wrapper around
devm_request_threaded_irq(), it also benefits from this
automatic logging.

Remove the now-redundant dev_err() and dev_err_probe() calls
in tty drivers that follow these devm_request_*_irq()
functions, as the core now provides more detailed diagnostic
information on failure.
