Subject: [PATCH] hid: intel-ish-hid: Fix uninitialized variable 'rv' in ish_fw_xfer_direct_dma
Date: Fri,  4 Oct 2024 13:29:44 +0530	[thread overview]
Message-ID: <20241004075944.44932-1-surajsonawane0215@gmail.com> (raw)

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.
