[PATCH RESEND 1/2] media: i2c: isl7998x: Inline i2c_check_functionality() check

From: Thorsten Blum <blum@kernel.org>
Date: 2026-09-09 08:21:18

Inline the i2c_check_functionality() check, since the function returns a
boolean status rather than an error code.

Wolfram, could you please apply this last conversion, since this patch
has not been applied yet despite several resends since April? Thanks.

[PATCH RESEND 2/2] i2c: Change return type to bool for i2c_check_functionality()

From: Thorsten Blum <blum@kernel.org>
Date: 2026-09-09 08:21:29

i2c_check_functionality() returns a bool - change the return type from
int to bool and update the comment accordingly.

both patches merged to i2c/i2c.

For some reason I don't see anywhere in my mailbox your patch
1/1, I had to fish it out from patchwork.

Thanks,
Andi

I might have messed up the git send-email recipients and my config ended
up adding you only to patch 2/2. Apologies!

Thanks,
Thorsten
