There is a case where NULL can be a valid return value for
ti_clk_get_reg_addr, specifically the case where both the provider index
and register offsets are zero. In this case, the current error checking
against a NULL pointer will fail. Thus, change the API to return a
ERR_PTR value in an error case, and change all the users of this API to
check against IS_ERR instead.

Looks good to me.

Can this patch be queued separately by Mike or is there some
dependency to this series?
Without this patch, patch #10 in the set causes a boot failure on omap3,
because the specific NULL value is returned for iva2_ck and the clock
register fails. This in turn breaks hwmod registration because iva2_ck
is missing.
I would just queue this patch as part of this series to avoid any trouble.
Other than wondering about the above and the dts related comments,
this series works for me with PM tests.
I hope to post a series with the dts related comments fixed later today.
