Linux Kernel UFS SCSI Driver WARN_ON_ONCE Removal Vulnerability

Vulnerability

A vulnerability in the Linux kernel's UFS SCSI driver has been addressed by removing a WARN_ON_ONCE() call from the UIC command completion function. The issue arose because the UIC completion interrupt could be disabled while a command was being processed. When the interrupt was reenabled, it triggered a warning due to the absence of a command, indicating a potential flaw in the interrupt handling process.

Impact

The removal of the WARN_ON_ONCE() call prevents unnecessary warning messages from being generated, which could obscure more critical issues that may arise during UIC command processing.
