Subject: [PATCH] bus: fsl-mc: Use strscpy() instead of strscpy_pad()
Date: Sun, 13 Apr 2025 19:29:50 +0200	[thread overview]
Message-ID: <20250413172948.207258-4-thorsten.blum@linux.dev> (raw)

Both destination buffers are already zero-initialized, making strscpy()
sufficient for safely copying 'obj_type'. The additional NUL-padding
performed by strscpy_pad() is unnecessary.

If the destination buffer has a fixed length, strscpy() automatically
determines its size using sizeof() when the argument is omitted. This
makes the explicit size arguments unnecessary.

No functional changes intended.
