From dd78982d580aa61c39bfd13940140e5830f489b2 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Mon, 26 Nov 2018 16:28:07 -0800 Subject: minui: GRSurface::Create() computes data_size on its own. GRSurface::Create() doesn't need to rely on caller specifying the buffer size, as it can compute that info based on the given args. This CL also uses `size_t` for all the parameters in GRSurface::Create(). Test: Run recovery_unit_test on marlin. Test: Build and boot into blueline recovery. `Run graphics test`. Test: Build and boot into blueline charger mode.
