Subject: [PATCH v2 1/1] ACPI: processor: idle: Replace strlcat() with better alternative
Date: Tue, 17 Mar 2026 09:01:06 +0100	[thread overview]
Message-ID: <20260317080218.1814693-1-andriy.shevchenko@linux.intel.com> (raw)

strlcpy() and strlcat() are confusing APIs and the former one already gone
from the kernel. In preparation to kill strlcat() replace it with the better
alternative.

Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

v2: moved to scnprintf() to avoid GCC warning (clang was and is okay)
