drm/msm: use strscpy instead of strncpy
[ 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));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fixes: f97decac5f4c ("drm/msm: Support multiple ringbuffers")
