msm: mdss: Prevent NULL pointer access

Current code has scope of dereferencing an already
NULL variable. Implementing proper error handling
for NULL variable.

msm: mdss: Avoid variable overloading

A particular variable is overloaded and used in 2 different
contexts. This causes overwriting of original value and leads
to incorrect error handling. This code adds a new variable to
avoid such condition.

pwm: qpnp: modify to use pwm_config_us() for some qcom drivers

Kernel 3.10 defines pwm_config() to use nanosecond parameters, but
now some qcom drivers still use pwm_config() to pass microsecond
parameters. pwm-qpnp driver has already provided a new API called
pwm_config_us() to support microsecond parameters, so we should
modify to use pwm_config_us() instead of pwm_config() for these
drivers.

msm: bam_dmux: tune downlink polling parameters

This change disables the BAM DMUX adaptive timer - this is to address
concerns about drops in TCP throughput for some use cases with the timer
enabled.  It also sets the aggregation to 3ms to save power while not
compromising performance. Power tests show a savings of 3-4% (compared to
having the timer poll the BAM pipe every 1 ms) for LTE (40Mbps downlink and
25Mbps uplink) and HSPA (7Mbps downlink and 384Kbps uplink) with no
degradation in performance.

msm: bam_dmux: add loopback support

Bam dmux is currently very difficult to isolate and provide measurements
for common metrics, such as throughput and latency.

Add hooks into bam_dmux to allow for a seperate dynamically
loadable loopback module. This allows bam dmux to be isolated, and to
provide more accurate measurements of the above metrics.

msm: bam_dmux: Fix race condition during SSR

BAM DMUX drivers set the global flags to identify the SSR during
SUBSYS_BEFORE_SHUTDOWN notification, but the flags change is not reflected
in some code paths like msm_bam_dmux_write().

Add the SSR flag check and SRCU locking to complete all pending bam dmux
writes before returning the control in SSR call back function for
SUBSYS_BEFORE_SHUTDOWN notification.
