Linus Torvalds ecd5d67ad6 pwm: A set of fixes for pwm core and various drivers 
The first three patches handle clk_get_rate() returning 0 (which might
 happen for example if the CCF is disabled). The first of these was found
 because this triggered a warning with clang, the two others by looking
 for similar issues in other drivers. Similar patches were merged earlier
 for v6.15-rc1 in commit 92b71befc3 ("Merge tag
 'objtool-urgent-2025-04-01' of
 git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip").
 The remaining three fixes address issues in the new waveform pwm API.
 Now that I worked on this a bit more, the finer details and corner cases
 are better understood and the code is fixed accordingly.
