[ Upstream commit d7fd8634f48d76aa799ed57beb7d87dab91bde80 ]
Using strncpy can result in non-NULL-terminated destination string. Use strscpy instead. This fixes following warning:
drivers/gpu/drm/msm/msm_fence.c: In function ‘msm_fence_context_alloc’: drivers/gpu/drm/msm/msm_fence.c:25:9: warning: ‘strncpy’ specified bound 32 equals destination size [-Wstringop-truncation] 25 | strncpy(fctx->name, name, sizeof(fctx->name)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
