[PATCH AUTOSEL 5.10 1/4] usb: host: max3421-hcd: Add missing spi_device_id table

[Sasha Levin]

From: Alexander Stein <alexander.stein@mailbox.org>

[ Upstream commit 41d5e3806cf589f658f92c75195095df0b66f66a ]

"maxim,max3421" DT compatible is missing its SPI device ID entry, not
allowing module autoloading and leading to the following message:
 "SPI driver max3421-hcd has no spi_device_id for maxim,max3421"

Fix this by adding the spi_device_id table.

[PATCH AUTOSEL 5.10 3/4] usb: gadget: aspeed: Add NULL pointer check in ast_vhub_init_dev()

[Sasha Levin]

From: Chenyuan Yang <chenyuan0y@gmail.com>

[ Upstream commit 8c75f3e6a433d92084ad4e78b029ae680865420f ]

The variable d->name, returned by devm_kasprintf(), could be NULL.
A pointer check is added to prevent potential NULL pointer dereference.
This is similar to the fix in commit 3027e7b15b02
("ice: Fix some null pointer dereference issues in ice_ptp.c").

This issue is found by our static analysis tool
