[PATCH v3 2/8] i2c: riic: Use local `dev` pointer in `dev_err_probe()`

From: Prabhakar
Date: Fri Dec 27 2024 - 06:52:36 EST


From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Update the `riic_init_hw()` function to use the local `dev` pointer in
calls to `dev_err_probe()`. Previously, `riic_init_hw()` used
`riic->adapter.dev` in error reporting. Since this function is invoked
during the probe phase, the I2C adapter is not yet initialized, leading to
`(null) ...` being printed in error messages. This patch fixes the issue
by consistently using the local `dev` pointer, which points to
`riic->adapter.dev.parent`.
