Subject: mtd: nand: brcmnand: Zero bitflip is not an error

From: Albert Hsieh <[email protected]>

[ Upstream commit e44b9a9c135727f3410e029910275f40681dc8bc ]

A negative return value of brcmstb_nand_verify_erased_page() indicates a real bitflip error of an erased page, and other return values (>= 0) show the corrected bitflip number. Zero return value means no bitflip, but the current driver code treats it as an error, and eventually leads to falsely reported ECC error.
