The subject says that the change adds q6asm_get_hw_ptr but here it says
that calculation of hw_ptr is moved. Where is it moved out of or from?

Currently the commit message is confusing.

It seems to be potential confusing split with commit.
("ASoC: qcom: q6asm-dai: use q6asm_get_hw_pointer") where calculation
of hw_ptr was implemented in q6asm-dai.c.

Ideally this should be sorted but it seems it was not initially.
