No line breaks between tags (see `git log`).

That's a separate patch. Always.

No big deal, but I've looked at git log and found previous commit 
b538304da785 ("clk: qcom: gcc-sdm660: Add missing modem reset") [1] that 
did similar things, but in a single patch, so I did the same.

Will fix in v2.
