[ Upstream commit 38212b2a8a6fc4c3a6fa99d7445b833bedc9a67c ]
Since __qcom_scm_is_call_available() returns bool, have it return false instead of -EINVAL if an invalid SMC convention is detected.
This fixes the Smatch static checker warning:
drivers/firmware/qcom_scm.c:255 __qcom_scm_is_call_available() warn: signedness bug returning '(-22)'
