net: ethernet: adi: adin1110: Check return value of devm_gpiod_get_optional() in adin1110_check_spi()

2026-02-04T03:11:58+00:00

The devm_gpiod_get_optional() function may return an ERR_PTR in case of genuine GPIO acquisition errors, not just NULL which indicates the legitimate absence of an optional GPIO. Add an IS_ERR() check after the call in adin1110_check_spi(). On error, return the error code to ensure proper failure handling rather than proceeding with invalid pointers.

net: rename netns_local to netns_immutable

2025-03-04T11:44:48+00:00

The name 'netns_local' is confusing. A following commit will export it via netlink, so let's use a more explicit name. Reported-by: Eric Dumazet Suggested-by: Kuniyuki Iwashima Signed-off-by: Nicolas Dichtel Reviewed-by: Kuniyuki Iwashima Signed-off-by: Paolo Abeni

net: ethernet: adi: adin1110: Fix some error handling path in adin1110_read_fifo()

2024-10-07T23:49:43+00:00

If 'frame_size' is too small or if 'round_len' is an error code, it is likely that an error code should be returned to the caller. Actually, 'ret' is likely to be 0, so if one of these sanity checks fails, 'success' is returned. Return -EINVAL instead.

net: ethernet: adi: adin1110: Reduce the MDIO_TRDONE poll interval

2024-02-27T10:27:20+00:00

In order to do a clause 22 access to the PHY registers of the ADIN1110, we have to write the MDIO frame to the ADIN1110_MDIOACC register, and then poll the MDIO_TRDONE bit (for a 1) in the same register. The device will set this bit to 1 once the internal MDIO transaction is done. In practice, this bit takes ~50 - 60 us to be set. The first attempt to poll the bit is right after the ADIN1110_MDIOACC register is written, so it will always be read as 0. The next check will only be done after 10 ms, which will result in the MDIO transactions taking a long time to complete. Reduce this polling interval to 100 us. Since this interval is short enough, switch the poll function to readx_poll_timeout_atomic() instead.
