[PATCH] scsi: qedi: Replace all non-returning strlcpy with strscpy

From: Azeem Shaikh
Date: Wed May 17 2023 - 10:35:17 EST


strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
No return values were used, so direct replacement is safe.
