The preferred coding style is not to start new lines with operators.

minor nitpick: if you express this as GENMASK(18, 16), it will be a bit
easier to cross-check with the datasheet, since both 18 and 16 are more
representative than 0x7.

also here: (((x) & GENMASK(18, 16)) >> 16)

and here: (((x) << 16) & GENMASK(18, 16))
