Re: [PATCH v3 0/2] firewire: core: validate descriptor and sub-block lengths in fw_core_add_descriptor()

Hi Takashi,

Thanks for applying the series to the for-next branch!

Regarding the change in generate_config_rom():

I dropped that specific change from this patchset to keep the series 
strictly focused on the out-of-bounds issue in fw_core_add_descriptor(). 

`WARN_ON(j != config_rom_length)` acts as an assertion that the ROM block 
traversal matched the expected length. Replacing it with pr_warn() and 
clamping `config_rom_length = j` avoids a kernel warning splat, but if 
j != config_rom_length occurs, it indicates an unexpected state during 
ROM generation rather than a standard runtime condition.

If you feel handling length mismatches gracefully via pr_warn() and updating 
config_rom_length is preferred over the WARN_ON assertion, I would be happy 
to send a follow-up patch for it.

Thanks,
Sreeraj
