+Subject: [PATCH] mtd: rawnand: qcom: fix memory corruption that causes panic
+
+This patch fixes a memory corruption that occured in the
+qcom-nandc driver since it was converted to nand_scan().
+
+On boot, an affected device will panic from a NPE at a weird place:
+| Unable to handle kernel NULL pointer dereference at virtual address 00000000
+| pgd = (ptrval)
+| [00000000] *pgd=00000000

+| [<c059d274>] (qcom_nandc_probe) from [<c0567f00>] (platform_drv_probe+0x34/0x70)
+
+The problem is that the nand_scan()'s qcom_nand_attach_chip callback
+is updating the nandc->max_cwperpage from 1 to 4. This causes the
+sg_init_table of clear_bam_transaction() in the driver's
+qcom_nandc_block_bad() to memset much more than what was initially
+allocated by alloc_bam_transaction().
+
+Hence, this patch restores the old behavior by performing the
+alloc_bam_transaction() after the chip was identified.
