Patch Review

**Status: Clean**

The change replaces:
```c
ret =3D i2c_check_functionality(client->adapter,
                              I2C_FUNC_SMBUS_BYTE_DATA);
if (!ret) {
```
with:
```c
if (!i2c_check_functionality(client->adapter, I2C_FUNC_SMBUS_BYTE_DATA)) {
```

This is correct because:

1. **`i2c_check_functionality()` returns boolean, not an error code.** Assi=
gning its result to `ret` is misleading =E2=80=94 it suggests an error-code=
 pattern (check `ret < 0`), but the old code was already checking `!ret` wh=
ich is the boolean pattern. Inlining makes the intent clearer.

2. **`ret` is still used later in the function** (line 1213: `ret =3D devm_=
regulator_bulk_get_enable(...)`) so there is no risk of an unused-variable =
warning from removing this one assignment.

3. **No functional change** =E2=80=94 the behavior is identical before and =
after.

The commit message is accurate and concise. The patch already carries a Rev=
iewed-by tag.
