mtd: jedec_probe: initialise make sector erase command variable
In the commit 08968041bef437ec363623cd3218c2b083537ada (mtd: cfi_cmdset_0002: make sector erase command variable) introdused a field sector_erase_cmd. In the same commit initialisation of cfi->sector_erase_cmd made in cfi_chip_setup() (file drivers/mtd/chips/cfi_probe.c), so the CFI chip has no problem: ... cfi->cfi_mode = CFI_MODE_CFI; cfi->sector_erase_cmd = CMD(0x30); ... But for the JEDEC chips this initialisation is not carried out, so the JEDEC chips have sector_erase_cmd == 0. This patch adds the missing initialisation.
