While trying to find out why that happened I inspected the code in that function and found that there's: - a missing check on the return value of a kzalloc() call - a potential memory leak in it Both fixes have nothing to do with my original crash (for which I'll open a separate thread). Changes since v1: - collected Liang's Acked-by's (thank you!) - rebased on top of v5.1-rc1 Martin Blumenstingl (2): mtd: rawnand: meson: add missing ENOMEM check in meson_nfc_read_buf() mtd: rawnand: meson: fix a potential memory leak in meson_nfc_read_buf drivers/mtd/nand/raw/meson_nand.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) -- 2.21.0
