[PATCH v3 1/2] staging: octeon: ethernet-spi: replace pr_err with dev_err

From: Ayush Mukkanwar

Date: Thu Apr 02 2026 - 07:48:36 EST

Replace pr_err() calls with dev_err() to include device information
in log messages. The device pointer is passed through the interrupt
handler via dev_id, which is changed from &number_spi_ports to
netdev pointer in request_irq and free_irq.
