When the body of a case statement is empty, it is well understood that
it is intentional and explicit fallthrough statements are not required.
Drop them.

In case of error, the function devm_kzalloc() and devm_kcalloc() return
NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Presumably we want to use this match table so add a module device table
and set the driver match pointer appropriately.

The digital delay allows outputs to be delayed from 8 to 1023 VCO
cycles. The delay step can be as small as half the period of the clock
distribution path. For example, a 3.2-GHz VCO frequency results in
156.25-ps steps. The digital delay value takes effect on the clock
output phase after a SYNC event.
This is required to support JESD204B subclass 1.

The LMK04832 is an ultra-high performance clock conditioner with JEDEC
JESD204B support and is also pin compatible with the LMK0482x family of
devices.
