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

2026-02-11T12:39:15+00:00

[ Upstream commit 78211543d2e44f84093049b4ef5f5bfa535f4645 ] 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: ethernet: adi: adin1110: Fix some error handling path in adin1110_read_fifo()

2024-10-17T13:24:25+00:00

[ Upstream commit 83211ae1640516accae645de82f5a0a142676897 ] 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.

2023-10-21T10:54:42+00:00

The spi_transfer struct has to have all it's fields initialized to 0 in this case, since not all of them are set before starting the transfer. Otherwise, spi_sync_transfer() will sometimes return an error.

net:ethernet:adi:adin1110: Fix forwarding offload

2023-09-11T07:30:22+00:00

Currently, when a new fdb entry is added (with both ports of the ADIN2111 bridged), the driver configures the MAC filters for the wrong port, which results in the forwarding being done by the host, and not actually hardware offloaded. The ADIN2111 offloads the forwarding by setting filters on the destination MAC address of incoming frames. Based on these, they may be routed to the other port. Thus, if a frame has to be forwarded from port 1 to port 2, the required configuration for the ADDR_FILT_UPRn register should set the APPLY2PORT1 bit (instead of APPLY2PORT2, as it's currently the case).

net: Replace all spi->chip_select and spi->cs_gpiod references with function call

2023-03-11T12:34:02+00:00

Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod members of struct spi_device to be an array. But changing the type of these members to array would break the spi driver functionality. To make the transition smoother introduced four new APIs to get/set the spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and spi->cs_gpiod references with get or set API calls. While adding multi-cs support in further patches the chip_select & cs_gpiod members of the spi_device structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.
