Subject: [PATCH 14/33] mtd: spi-nor: fix error handling in spi_nor_erase
The documenting comment of mtd_erase in mtdcore.c states:
Device drivers are supposed to call instr->callback() whenever
the operation completes, even if it completes with a failure.
Currently the callback isn't called in case of failure. Fix this.
