The scst_wait_event_interruptible_lock_irq() function now implicitly checks for pending signals. Therefore, there is no need to check for these signals explicitly. This patch replaces the explicit check with a simple evaluation of the function's return value. This patch doesn't change any functionality.
The prepare_to_wait_exclusive_head() function was modified in commit d8894cb ("scst.h: Refactor wait_event_locked() to enhance usability and clarity"). It now returns an error if the current interruptible thread has pending signals. This patch introduces the scst_wait_for_cmd() helper function for the scst_cmd_thread(). This new function handles the return value of the prepare_to_wait_exclusive_head() appropriately. This patch fixes the following Coverity complaint: CID 321410 (#1 of 1): Unchecked return value (CHECKED_RETURN) check_return: Calling prepare_to_wait_exclusive_head without checking return value.
