This small change prevents an unused variable from being initialized, throwing a warning during compilation, thus ending fatally.

Make finished with errors
* Use the new debounce algorithm in dactyl/matrix.c [#2065]
This incorporates the fixed/optimized debounce code added to
quantum/matrix.c in:
* 508eddf8ba
* 4c6960835c
* 32f88c0717
* f403028974
* a06115df19
* Fix the row/column swap in dactyl [#2065]
With a column-driven keyboard, reading from the mcp23081 returns a
column-state, which takes some extra work to translate into the
row-state used in the actual matrix. The ergodox_ez code sidestepped
that problem by calling rows "columns" and columns "rows." With this
change, the dactyl now calls rows "rows" and columns "columns."
* Cleanup: variable names, documentation [#2065]
* Support MATRIX_MASKED in dactyl/matrix.c [#2065]
* Only unselect one col in unselect_col [#2065]
Bonus: saves one i2c transaction per matrix_scan!
* Implement COL2ROW in dactyl/matrix.c [#2065]
* Fix a typo in dactyl/matrix.c
This entirely doesn't matter. The PORT values are set during
init_keyboard and never change. They're repeatedly set to the same
thing. These PORT lines shouldn't even exist, but since they do, they
should at least look right.
* Implement COL_PINS/ROW_PINS for dactyl [#2065]
* Rename "mcp23018" to "expander" [#2065]
I honestly don't know whether/how well this code works with other I/O
expanders, but at least in theory, it should be generic enough to work
with others. Given that, the variable names shouldn't refer to a
specific model of expander.
* Remove matrix_power_up from dactyl/matrix.c [#2065]
It's commented out in quantum/matrix.c, and the dactyl has no power
up/down behavior beyond being unplugged (which goes to matrix_init), so
there's no sense keeping it around.
* Only initialize expander_input_mask once [#2065]
...and rename input_mask to expander_input_mask, since now that it isn't
scoped to init_expander it isn't clear that it's only for the expander.
* Copy the ergodox_ez code to handwired/dactyl
Differences from the Ergodox:
* Use QMK_SUBPROJECT_H instead of QMK_KEYBOARD_H, since it's under
handwired
* Omitted several keymaps. They'll eventually be broken (since the
Dactyl has fewer keys), and I don't want to try to fix them.
* Omitted the keymap images for the default layout, since they depict
a different keyboard.
* Everything that said Ergodox now says Dactyl, naturally.
* [whitespace] Delete trailing whitespace
My editor does this automatically so it's just gonna keep cropping up...
* Cut the dactyl down to the right number of columns
(Remember, throughout matrix.c, everything called "row" is really a
column, and vice-versa).
* Remove LED-related code
* Tighten up the Dactyl's build options
* Whitespace cleanup in twimaster.c
* Hardtabs -> spaces
* No more trailing whitespace
* Typo fix
* Correct the CPU frequency units
The Teensy's CPU definitely doesn't run at 16 petahertz...
* Restore access to ONEHAND_ENABLE
I turned it off in 26d47cb42622d990a7c3335e7fcc151aa3edfbf0 while
desperately debugging; I just wanted to ensure it wasn't causing the
problem I was seeing. It was not, in fact, causing the problem, so it's
back.
Also fixed the swap matrix in dactyl.c, since it still referred to
columns that exist in the Ergodox but not the Dactyl.
* Clearer phrasing about TWI's effect on scan rate
* Fix up the Dactyl's firmware-loading instructions
Sadly, the Dactyl has no hole for the onboard reset button.
* Dvorak keymap for the Dactyl
* The Erincalling Layout
* Erincalling layout: Add a := key
I've been working in Go, which uses := a lot, and it's awkward to type
in this layout.
* Dactyl README: link to the dactyl-keyboard repo
* Add a missing copyright line
I don't know how much this matters? Honestly, it's enough for me that my
name is on the git commit. But hey, let's be consistent until there's a
specific reason not to be, right?
* Dactyl: remove commented-out code
I hate it I hate it I hate it
There's not even any information about what it was trying to do!!!! >:(
* Add a note about the row/column ridiculousness
* [whitespace] realign some constants
* Don't claim B4 is tied to VCC
It doesn't matter at all? I honestly don't know what the reason ever
was. It looks like it dates back to the original ErgoDox and I've never
seen one sentence about the purpose.
I've been skipping that wire for some time, and I promise it works fine.
* Dactyl keymaps: Send RALT for right-hand alt key
Not terribly important but I just like things tidy OK
* typo fix
* Refer to "dactyl.h" explicitly
QMK_SUBPROJECT_H has been working locally, but fails in CI. Strange!
* Dactyl: Don't use QMK_SUBPROJECT_H at all
It's still breaking in CI, even though it was a never a problem locally.
