hci_update_accept_list_sync is returning the filter based on the error
but that gets overwritten by hci_le_set_addr_resolution_enable_sync
return instead of using the actual result of the likes of
hci_le_add_accept_list_sync which was intended.

v2: Use u8 filter_policy instead of int ret as variable to store the result.

Just to put you in the loop in case you have not noticed it yet: there 
seems to be some kind of regression introduced by this patch. See 
comment #5 of ticket 215768 where Damien Thébault bisected the kernel [1].

Thx for CCing the regressions list.

[TLDR: I'm adding this regression report to the list of tracked
regressions; all text from me you find below is based on a few templates
paragraphs you might have encountered already already in similar form.]

To be sure below issue doesn't fall through the cracks unnoticed, I'm
adding it to regzbot, my Linux kernel regression tracking bot:

#regzbot ^introduced 80740ebb7e1ad
#regzbot title net: bluetooth: can't suspend while bluetooth is enabled.
#regzbot ignore-activity
#regzbot from: plum <plumerlis@gmail.com>
#regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215768

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply -- ideally with also
telling regzbot about it, as explained here:
https://linux-regtracking.leemhuis.info/tracked-regression/

Reminder for developers: When fixing the issue, add 'Link:' tags
pointing to the report (the mail this one replied to), as the kernel's
documentation call for; above page explains why this is important for
tracked regressions.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.

TWIMC: this mail is primarily send for documentation purposes and for
regzbot, my Linux kernel regression tracking bot. These mails usually
contain '#forregzbot' in the subject, to make them easy to spot and filter.

#regzbot fixed-by: a9a347655d224fa284187

That fix landed in bluetooth-next. I wonder if that fix would better
have been merged in this cycle, as that will mean many users are exposed
to this for at least three more weeks, but whatever.
