[PATCH] hid: intel-ish-hid: Fix uninitialized variable 'rv' in ish_fw_xfer_direct_dma

From: SurajSonawane2415
Date: Fri Oct 04 2024 - 04:00:58 EST


Fix the uninitialized symbol 'rv' in the function ish_fw_xfer_direct_dma
to resolve the following warning from the smatch tool:
drivers/hid/intel-ish-hid/ishtp-fw-loader.c:714 ish_fw_xfer_direct_dma()
error: uninitialized symbol 'rv'.
Initialize 'rv' to 0 to prevent undefined behavior from uninitialized
access.
