So, here is my second approach, now avoiding probe() and targetting the init call. To avoid boilerplate, I introduced macros similar to module_driver(). It still feels a little adventurous because of hard-coding '.remove' and '.driver.suppress_bind_attts' in the macro and trusting various driver types (like platform and PCI) to follow this structure. Having all this said, it works nicely on my Renesas Salvator-XS (R-Car M3-N). No reply from buildbot yet, but it is RFC only, so I'll send it out already. A git branch can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/wdt-suppress-attr Looking forward to comments.
