commit d41bff05a61fb539f21e9bf0d39fac77f457434e upstream.
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.
