mtd: maps: Fix refcount leak in ap_flash_init

2022-08-25T09:17:50+00:00

[ Upstream commit 77087a04c8fd554134bddcb8a9ff87b21f357926 ]

of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

mtd: fixup CFI on ixp4xx

2022-01-20T08:19:19+00:00

commit 603362b4a58393061dcfed1c7f0d0fd4aba61126 upstream.

drivers/mtd/maps/ixp4xx.c requires MTD_CFI_BE_BYTE_SWAP to be set
in order to compile.

drivers/mtd/maps/ixp4xx.c:57:4: error: #error CONFIG_MTD_CFI_BE_BYTE_SWAP required

This patch avoids the #error output by enforcing the policy in
Kconfig. Not sure if this is the right approach, but it helps doing
randconfig builds.

mtd: pismo: Simplify getting the adapter of a client

We have a dedicated pointer for that, so use it. Much easier to read and
less computation involved.

pxa2xx-flash is the only user of ioremap_cached, which is an alias
for ioremap_cache anyway.
