From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> [ Upstream commit ec0da06337751b18f6dee06b6526e0f0d6e80369 ] When meson_nfc_nand_chip_cleanup() is called, it will call: meson_nfc_free_buffer(&meson_chip->nand); nand_cleanup(&meson_chip->nand); nand_cleanup() in turn will call nand_detach() which calls the .detach_chip() which is here meson_nand_detach_chip(). meson_nand_detach_chip() already calls meson_nfc_free_buffer(), so we could double free some memory. Fix it by removing the unneeded explicit call to meson_nfc_free_buffer().
