Alexander Usyskin 2c34622d9c mei: trace: treat reg parameter as string 
[ Upstream commit 06d5a7afe1 ]

The commit
afd2627f72 ("tracing: Check "%s" dereference via the field and not the TP_printk format")
forbids to emit event with a plain char* without a wrapper.

The reg parameter always passed as static string and wrapper
is not strictly required, contrary to dev parameter.
Use the string wrapper anyway to check sanity of the reg parameters,
store it value independently and prevent internal kernel data leaks.

Since some code refactoring has taken place, explicit backporting may
be needed for kernels older than 6.10.
