flash_lock: fix length being passed
This patch fixes the 'length' calculation. Making it: + mtdLockInfo.length = (num_sectors - 1) * mtdInfo.erasesize; Rather: - mtdLockInfo.length = num_sectors * mtdInfo.erasesize; Say there are 240 blocks present in the device. Then: offset starts from: 0x0 and full size of device: 0x1E00000 doing: 240 * 0x20000 gives -> 0x1E00000 But last block address should be 0x1DE0000 (which spans for 0x20000 bytes, adding upto size of 0x1E00000) Signed-off-by: Vimal Singh <vimalsingh@ti.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
