Commit 1a2f474d328f handles block _reads_ separately with plain-I2C
adapters, but the problem described with regmap-i2c not handling
SMBus block transfers (i.e. read and writes) correctly also exists
with writes.

As workaround, this patch adds a block write function the same way
1a2f474d328f adds a block read function.

Fixes: 1a2f474d328f ("usb: typec: tps6598x: handle block reads separately with plain-I2C adapters")
Fixes: 0a4c005bd171 ("usb: typec: driver for TI TPS6598x USB Power Delivery controllers")

You are missing a "from" line with address that matches your SoB
address.

That's because I currently cannot send patch mails from my company account
as our MTA breaks diffs.

I understand, but you can have a separate "From line" in your patch,
i.e. you send the patch using one address, and have an extra "From
line" (outside of the mail header) with another address.

That other From line will be interpreted as the author address, and
it should match your SoB address.


Try something like this in a branch where this patch is the HEAD:

% export MY_COMMIT=$(git show -s --pretty=%h HEAD)
% git reset HEAD^
% GIT_COMMITTER_IDENT='Nikolaus Voss <nikolaus.voss@xxxxxxxxxxxxxxxxxxxxx>' \
GIT_AUTHOR_IDENT='Nikolaus Voss <nikolaus.voss@xxxxxxxxxxxxxxxxxxxxx>' \
git commit -a -C $MY_COMMIT

Correction here:

% GIT_COMMITTER_IDENT='Nikolaus Voss <nikolaus.voss@xxxxxxxxxxxxxxxxxxxxx>' \
GIT_AUTHOR_IDENT='Nikolaus Voss <nikolaus.voss@xxxxxxxxxxxxxxxxxxxxx>' \
git commit -a -C $MY_COMMIT --reset-author

That "--reset-author" was missing. Sorry for that.

Thanks, Heikki, I'll give it a try...
