isp1760_field_set() may access the udc->fields array beyond the size
of DC_FIELD_MAX up to HC_FIELD_MAX, which is (now) bigger. Increase
the buffer size to max(DC_FIELD_MAX,HC_FIELD_MAX) to avoid possible
overflow.

Where exactly does the problem manifest? There is no comprehensible bug
description here from you..
Though I guess isp1760_set_pullup() call site is concerned?

Please make sure to run your changes through checkpatch.pl and the
compiler first. They are both not happy at the moment.

Yes, when called from isp1760_udc_init_hw()
+ When isp1760_udc_init_hw() calls isp1760_set_pullup(),

Mea culpa... Sent earlier version.
There should be only one warning on "Comparisons should place
the constant on the right side of the test" when comparing two
constants.
Updated patch follows.

When isp1760_udc_init_hw() calls isp1760_set_pullup(), its call of
isp1760_field_set() may access the udc->fields array beyond the size
of DC_FIELD_MAX up to HC_FIELD_MAX, which is (now) bigger. Increase
the buffer size to max(DC_FIELD_MAX,HC_FIELD_MAX) to avoid possible
overflow.

This will fix the access, but not the main issue, so this is not
correct. The isp1760_set_pullup should pass to isp1760_field_set
the hcd fields and not the udc ones.
I will send a proper fix for this. Thanks for reporting.
Cheers,
Rui
