msm_hs_handle_delta_cts tries to acquire port->lock already acquired
by the callee function msm_hs_isr. Change function name to follow
"_locked" convention.

Both tx and rx command_ptr_ptr are of type u32*. While allocating
memory for it, sizeof(u32 *) is used as part of kmalloc API instead
of sizeof(u32). ADM Hardare requires size of command_ptr_ptr as 1 Word.
Both sizeof(u32 *) and sizeof(u32) are same on 32-bit architecture
whereas sizeof(u32 *) would be different in size compare to sizeof(u32)
on anyother architecture.

Hence correct usage of sizeof(command_ptr_ptr) for Tx and Rx with
kmalloc and dma_(map/unmap)_single APIs.

linux/tty_flip.h is included in linux/serial_core.h. But this may (and
will) change in the future. Then we would get build errors such as:
.../tty/serial/max3107.c: In function ‘put_data_to_circ_buf’:
.../tty/serial/max3107.c:149:2: error: implicit declaration of function ‘tty_insert_flip_string’

So fix all the drviers which call tty flip buffer helpers to really
include linux/tty_flip.h. And also make sure that those include
linux/tty.h when operating with struct tty_struct.

This driver supports UART-DM HW on MSM platforms. It uses the on
chip DMA to drive data transfers and has optional support for UART
power management independent of Linux suspend/resume and wakeup
from Rx.

The driver was originally developed by Google. It is functionally
equivalent to the version available at:
http://android.git.kernel.org/?p=kernel/experimental.git
the differences being:
1) Remove wakelocks and change unsupported DMA API.
2) Replace clock selection register codes by macros.
3) Fix checkpatch errors and add inline documentation.
4) Add runtime PM hooks for active power state transitions.
5) Handle error path and cleanup resources if required.
