On malfunctioning hardware, timeout error messages can appear thousands of times, creating unnecessary system pressure and log bloat. This patch makes two improvements: 1. Replace dev_err() with dev_err_ratelimited() to prevent log flooding when hardware errors persist 2. Remove the redundant timeout value parameter from the error message, as 'ret' is always zero in this error path These changes reduce logging overhead while maintaining necessary error reporting for debugging purposes.
