mtd: mtd_oobtest: Remove redundant assignment to err
Variable err is set to zero but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: drivers/mtd/tests/oobtest.c:626:4: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores]. drivers/mtd/tests/oobtest.c:603:4: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores]. drivers/mtd/tests/oobtest.c:579:4: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores]. drivers/mtd/tests/oobtest.c:556:4: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores]. drivers/mtd/tests/oobtest.c:532:3: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores]. drivers/mtd/tests/oobtest.c:509:3: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores].
