drm: remove the newline for CRC source name.
[ Upstream commit 72a848f5c4
]
userspace may transfer a newline, and this terminating newline
is replaced by a '\0' to avoid followup issues.
'len-1' is the index to replace the newline of CRC source name.
v3: typo fix (Sam)
v2: update patch subject, body and format. (Sam)
