This change will fix NULL pointer dereference while reading from spi nand flash in oobbuf. The multipage read features is only to read with ecc for raw read/write the the access is page wise due to mtd layer will request only one page at a time. So don't increment oobbuf for every page while reading if already bitflips are present in spi nand flash. if so data abort will happen due to NULL pointer dereference. error: NAND read: device 0 offset 0x4480000, size 0x1000 data abort pc : [<4a9515ec>] lr : [<44000e18>] reloc pc : [<4a9515ec>] lr : [<44000e18>] sp : 4a77f6f4 ip : bbfff3dc fp : 4a783510 r10: 4a97bb40 r9 : 4a77feb0 r8 : 44000e0c r7 : 4a97ca2c r6 : 0000000f r5 : 00000004 r4 : 00000003 r3 : ffffffff r2 : 000001f4 r1 : 000000ff r0 : 44000e0c Flags: nzCv IRQs off FIQs off Mode SVC_32 Resetting CPU ... resetting ...
