Hi all,
After merging the bluetooth tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
net/bluetooth/sco.c: In function 'sco_sock_setsockopt':
net/bluetooth/sco.c:862:3: error: cannot convert to a pointer type
862 | if (get_user(opt, (u32 __user *)optval)) {
|
ipv6_pinfo is initlialized by inet6_sk() which returns NULL.
Hence it can cause segmentation fault. Fix this by adding a
NULL check.

changes since v2:
- add more comments on enter_s2idle to explain why it is necessary to return
int even if its return value is never used.

- add more description in commit message.

Control Flow Integrity(CFI) is a security mechanism that disallows
changes to the original control flow graph of a compiled binary,
making it significantly harder to perform such attacks.
init_state_node() assign same function callback to different
function pointer declarations.

The cs-gpio is initailized by spi_get_gpio_descs() now. Remove the
chipselect.

Add "fsl,spi-only-use-cs1-sel" to fit i.MX8DXL-EVK.
Spi common code does not support use of CS signals discontinuously.
It only uses CS1 without using CS0. So, add this property to re-config
chipselect value.

SPI common code does not support using CS discontinuously for now.
However, i.MX8DXL-EVK only uses CS1 without CS0. Therefore, add a flag
is_only_cs1 to set the correct TCR[PCS].

Hi,
This patchset mainly fixes some recently discovered problems about CS for
LPSPI module on i.MX8DXLEVK.
Add the dt-bindings description for the new property.

Calling devm_spi_register_controller() too early will cause problem.
When probe failed occurs after calling devm_spi_register_controller(),
the call of spi_controller_put() will trigger the following warning dump.
