The return statement is incorrect, the error exit should be by
assigning ret with the error code and exiting via label out.

Currently there are error return paths in ffsReadFile that
exit via lable err_out that return and uninitialized error
return in variable ret. Fix this by initializing ret to zero.

When the max_segs of a mmc host is smaller than 512, the mmc
subsystem tries to use 512 segments if DMA MAP layer can merge
the segments, and then the mmc subsystem exposes such information
to the block layer by using blk_queue_can_use_dma_map_merging().

The kryo cpufreq driver reads the nvmem cell and uses that data to
populate the opps. There are other qcom cpufreq socs like krait which
does similar thing. Except for the interpretation of the read data,
rest of the driver is same for both the cases. So pull the common things

We are currently not enabling VBUS boost for cpcap when in host mode.
This means the VBUS is fed at the battery voltage level, which can cause
flakeyness enumerating devices.
Looks like the boost control for VBUS is CPCAP_BIT_VBUS_SWITCH that we
must enable in the charger for nice 4.92 V VBUS output. And looks like
we must not use the STBY pin enabling but must instead use manual VBUS
control in phy-cpcap-usb.
We want to do this in cpcap_charger_vbus_work() and also set a flag for
feeding_vbus to avoid races between USB detection and charger detection,
and disable charging if feeding_vbus is set.

genpd_lookup_dev(), is a bit unnecessary heavy, as it walks the gpd_list to
try to find a valid PM domain corresponding to the device's attached genpd.
Instead of walking the gpd_list, let's use the fact that a genpd always has
the ->runtime_suspend() callback assigned to the genpd_runtime_suspend()
function.
While changing this, let's take the opportunity to also rename
genpd_lookup_dev(), into dev_to_genpd_safe() to better reflect its purpose.

Every mvpp2 unit can use up to 8 buffers mapped by the BM (the HW buffer
manager). The HW will place the frames in the buffer pool depending on the
frame size: short (< 128 bytes), long (< 1664) or jumbo (up to 9856).
As any unit can have up to 4 ports, the driver allocates only 2 pools,
one for small and one long frames, and share them between ports.
When the first port MTU is set higher than 1664 bytes, a third pool is
allocated for jumbo frames.
This shared allocation makes impossible to use percpu allocators,
and creates contention between HW queues.
If possible, i.e. if the number of possible CPU are less than 8 and jumbo
frames are not used, switch to a new scheme: allocate 8 per-cpu pools for
short and long frames and bind every pool to an RXQ.
When the first port MTU is set higher than 1664 bytes, the allocation
scheme is reverted to the old behaviour (3 shared pools), and when all
ports MTU are lowered, the per-cpu buffers are allocated again.
