From fbb83e546ea4543ab0c59dcbfc5a5a1471ea1806 Mon Sep 17 00:00:00 2001 From: Jean-Marc Eurin Date: Thu, 21 Apr 2022 16:42:42 -0700 Subject: [PATCH] mtd: mtdoops: Fix the size of the header read buffer. The read buffer size depends on the MTDOOPS_HEADER_SIZE. Tested: Changed the header size, it doesn't panic, header is still read/written correctly.
