Linux Kernel iwlwifi Component: Unnecessary Warning Suppression After Firmware Error

A vulnerability in the Linux kernel's iwlwifi component has been addressed. The issue involved the iwl_trans_reclaim function, which incorrectly issued a warning when called while the firmware was not operational. However, if the function is invoked after a firmware error, indicating a pending restart, there is no need for a warning; the function should simply return without notification.

Impact

The vulnerability could lead to unnecessary warning messages being generated, which may cause confusion or obscure more relevant information in system logs.
