Subject: [PATCH v2 06/10] ipmi_si: Reuse si_to_str[] array in ipmi_hardcode_init_one()
Date: Fri,  2 Apr 2021 20:43:30 +0300	[thread overview]
Message-ID: <20210402174334.13466-7-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210402174334.13466-1-andriy.shevchenko@linux.intel.com>

Instead of making the comparison one by one, reuse si_to_str[] array
in ipmi_hardcode_init_one() in conjunction with match_string() API.
