With CONFIG_MTD=m and CONFIG_CRAMFS=y, we now get a link failure:
fs/cramfs/inode.o: In function `cramfs_mount':
inode.c:(.text+0x220): undefined reference to `mount_mtd'
fs/cramfs/inode.o: In function `cramfs_mtd_fill_super':
inode.c:(.text+0x6d8): undefined reference to `mtd_point'
inode.c:(.tex
The main rt5514 driver optionally calls into the SPI back-end to load
the firmware. This causes a link error when one driver selects rt5514
as built-in and another driver selects rt5514-spi as a loadable module:
sound/soc/codecs/rt5514.o: In function `rt5514_dsp_voice_wake_up_put':
rt5514.c:(.text
The new functions are only used when CONFIG_PM is enabled,
leading to a harmless warning:

ARM's v8.2 Extentions add support for Reliability, Availability and
Serviceability (RAS). On CPUs with these extensions system software
can use additional barriers to isolate errors and determine if faults
are pending.
Add cpufeature detection and a barrier in the context-switch
RAS Extension add a VSESR_EL2 register which can provides
the syndrome value reported to software on taking a virtual
SError interrupt exception. This patch supports to specify
this Syndrome.
In the RAS Extensions we can not set all-zero syndrome value
for SError, which means 'RAS error: Uncategor
The ARM64 RAS SError Interrupt(SEI) syndrome value is specific to the
guest and user space needs a way to tell KVM this value. So we add a
new ioctl. Before user space specifies the Exception Syndrome Register

set the guest ESR, If
If it is not RAS SError, directly inject virtual SError,
which will keep the old way. If it is RAS SError, firstly
let host ACPI module to handle it. For the ACPI handling,
if the error address is invalid, APEI driver will not
identify the address to hwpoison memory and can not notify
