* [PATCH v2 10/16] drivers: hv: move device_to_hv_device to use container_of_const() [not found] <20230111113018.459199-1-gregkh@linuxfoundation.org> @ 2023-01-11 11:30 ` Greg Kroah-Hartman 2023-01-12 14:04 ` Wei Liu 0 siblings, 1 reply; 2+ messages in thread From: Greg Kroah-Hartman @ 2023-01-11 11:30 UTC (permalink / raw) To: linux-kernel Cc: Greg Kroah-Hartman, K. Y. Srinivasan, Haiyang Zhang, Wei Liu, Dexuan Cui, linux-hyperv The driver core is changing to pass some pointers as const, so move device_to_hv_device() to use container_of_const() to handle this change. device_to_hv_device() now properly keeps the const-ness of the pointer passed into it, while as before it could be lost.
