Subject: [PATCH] i2c: muxes: i2c-mux-reg: use dev_err_probe() for deferred probe
Date: Sat, 4 Apr 2026 22:27:24 -0500 [thread overview]
Message-ID: <20260405032724.10085-1-adeel.m.zahid@gmail.com> (raw)
Use dev_err_probe() when the parent I2C adapter is not yet available.
This keeps deferred probe handling and logging consistent with the rest of the driver.
