Subject: [PATCH] rpmsg: glink: Replace strcpy() with strscpy()
Date: Thu, 11 Dec 2025 14:18:34 +0530	[thread overview]
Message-ID: <20251211-rpmsg-glink-strcpy-replace-v1-1-be06308e5724@oss.qualcomm.com> (raw)

From: Sudeepgoud Patil <quic_sudeepgo@quicinc.com>

Replace strcpy() with the safer strscpy() to address unsafe API
usage warnings[1] from static analysis tools, as strcpy() performs
no bounds checking on the destination buffer.
