stable inclusion from stable-5.10.80 commit 388cebfa7342cbf0ad5522c570d7630f241ebeac bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 42bb98e420d454fef3614b70ea11cc59068395f6 ]
The "card" string only holds 31 characters (and the terminating NUL). In order to avoid truncation, use a shorter card description instead of the current result, "Trident TVMaster TM5600/6000/60".
