From 293a6dfeb96129abebf1ad927fa9aedf03a66d34 Mon Sep 17 00:00:00 2001 From: Gary Bisson Date: Thu, 27 Aug 2020 10:51:14 +0200 Subject: [PATCH] fastboot: getvar: fix partition-size return value The size returned by 'getvar partition-size' should be in bytes, not in blocks as fastboot uses that value to generate empty partition when running format [1]. Note that the function was already returning the proper size in bytes for NAND devices (see struct part_info details).
