Proprietary chargers pull D+/- to specific voltages between 2.0-3.3V
(VLGC) for identification. The DM voltage may not exceed VLGC due
to pull-down resistor. Hence a proprietary charger is detected as
a Standard downstream port (SDP). Read line state to distinguish
between SDP and proprietary charger. The DP voltage would exceed
VLGC for proprietary chargers.
D- can be greater than VLGC when a low speed device is attached via
Accessory charger adapter (ACA-A). Hence mark the charger as ACA-A
if ID resistance is RID_A and D- > VLGC

1. Verifying if the size of memory allocation in ion_alloc() is aligned
by PAGE_SIZE at least. If it is not, this change makes the size to be
aligned by PAGE_SIZE.
2. Unmaps all mappings to the kernel and DMA address spaces when
destroying ion_buffer in ion_buffer_destroy(). This prevents leaks in
those virtual address spaces.
3. Makes the return value of ion_alloc() to be explicit Linux error code
when it fails to allocate a buffer.
4. Makes ion_alloc() implementation simpler. Removes 'goto' statement and
relavant call to ion_buffer_put().
5. Checks if the task is valid before calling put_task_struct() due
to failure on creating a ion client in ion_client_create().
6. Returns error when buffer allocation requested by userspace is failed.
