Subject: mtd: oxnas_nand: Allocating more than necessary in probe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b98e1995e4fa9030474a61ed0dbc033464fe5ea0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: oxnas_nand: Allocating more than necessary in probe()

We only need to allocate sizeof(struct oxnas_nand_ctrl) which is 192
bytes and not sizeof(struct nand_chip) which is a much larger 3056
bytes.
