From 1ca97ee9039293858988dc38ea3a8ff995b4950e Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Thu, 20 Feb 2025 15:58:07 +0100 Subject: [PATCH] mtd: mtdpart: Support MTD_SIZE_REMAINING with unallocated memory area If there is an unallocated memory area before the last, filling parting the size calculation for MTD_SIZE_REMAINING does not take this hole into account. Fix this by calculating the remaining size just based on total size and partition offset.
