Subject: [PATCH v1 1/1] fbdev: omapfb: Replace custom memparse() implementation
Date: Wed, 18 Oct 2023 06:47:25 +0300	[thread overview]
Message-ID: <20231018034725.1124006-1-andriy.shevchenko@linux.intel.com> (raw)

Our library has memparse() for parsing numbers with respective suffixes
suitable for memory sizes. Use it instead of custom implementation.
