usb: gadget: aspeed: Add NULL pointer check in ast_vhub_init_dev()

Browse source

[ Upstream commit 8c75f3e6a4 ]

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 3027e7b15b
("ice: Fix some null pointer dereference issues in ice_ptp.c").
