In function qca_setup, we set initial and operating speeds for
Qualcomm
Bluetooth SoC's. This block of code is common across different
Qualcomm Bluetooth SoC's. Instead of duplicating the code, created
a wrapper function to set the speeds. So that future coming SoC's
can use these wrapper functions to set speeds.

You changed this from:
/* One or the other speeds should be non zero. */
if (!qca_get_speed(hu, QCA_INIT_SPEED) &&
!qca_get_speed(hu, QCA_OPER_SPEED))
return -EINVAL;
There is no entry in the change log. What is the reason for this
change?
[Bala] : My bad i missed to add the log,as the above if for ROME chip,
having INIT or OPER speed is fine.
