Subject: [PATCH v1 1/1] string: Group str_has_prefix() and strstarts()
Date: Fri, 11 Jul 2025 11:55:14 +0300	[thread overview]
Message-ID: <20250711085514.1294428-1-andriy.shevchenko@linux.intel.com> (raw)

The two str_has_prefix() and strstarts() are about the same
with a slight difference on what they return. Group them in
the header.
