commit d2450c6937018d40d4111fe830fa48d4ddceb8d0 upstream.
The UDC core uses req->num_sgs to judge if scatter buffer list is used.
Eg: usb_gadget_map_request_by_dev. For f_fs sync io mode, the request
is re-used for each request, so if the 1st request->length > PAGE_SIZE,
and the 2nd request->length is <= PAGE_SIZE, the f_fs uses the 1st
req->num_sgs for the 2nd request, it causes the UDC core get the wrong
req->num_sgs value (The 2nd request doesn't use sg). For f_fs async
io mode, it is not harm to initialize req->num_sgs as 0 either, in case,
the UDC driver doesn't zeroed request structure.

When performing secure pool allocations, it's possible to
spuriously trigger pool refill attempts for the cached and
uncached pools. Fix this by adding a check to see if we're
performing a secure allocation or not, before refilling a pool.

It is expected that PLLs are already enabled since
boot usually enable PLLs. clk_hw_get_name can't be
used in clock pre-registration stage since hw->core
will be NULL.
PLL already enabled warning is valid in enable path.

When the buffer pointed to by test_virt_addr is allocated, there
is no synchronization with respect to checking if it is necessary
to allocate the buffer. This can lead to various adversarial
scenarios, where multiple concurrent allocations of the same
buffer can occur, resulting in memory leaks.
To avoid these scenarios, make the check and allocation of the
buffer atomic with respect to other accesses to test_virt_addr.

qti_flash_led_prepare() API is used by flash clients (E.g. Camera) to
query maximum current available for flash. Add support for this API
which initially returns maximum current that is supported for flash
LED module (2000 mA). Also, add a sysfs parameter under switch devices
to show max available flash current.
