If hif_read_reg() or hif_write_reg() fail in wilc_wlan_cleanup(),
it calls release_bus() and continues execution. But it leads to double
release_bus() call that means double unlock of g_linux_wlan->hif_cs mutex.
The patch adds return in case of failure.

Hi Linus,
Please pull the following fix from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
This addresses a refcounting bug that leads to a use-after-free.
Thanks!

Changes in v5:
* Made 'enable-method' for SMP per 'cpu' core instead of 'cpus'
node, in the DT files for BCM NSP and BCM4708.
Change in v4:
* Cleaned up kona_smp.c and associated DT file.
* Corrected documentation for DT bindings.
* Corrected secondary-boot-reg entry for bcm4708 DT file.
Change i
Add a compatible string "brcm,bcm-nsp-smp" for Broadcom's
Northstar Plus CPU to the 32-bit ARM CPU device tree binding
documentation file and create a new binding documentation for
Northstar Plus CPU.

Add SMP support for Broadcom's Northstar Plus SoC
cpu enable method. This changes also consolidates
iProc family's - BCM NSP and BCM Kona, platform
SMP handling in a common file.
Northstar Plus SoC is based on ARM Cortex-A9
revision r3p0 which requires configuration for ARM
Errata 764369 for SMP.

Well, s
Since only dma_declare_coherent_memory cares about
dma_init_coherent_memory returning part of flags as it return value,
move the condition to the former and simplify the latter. This in
