commit aaf0e80e684da35cd527491243583467ae7c75cb Author: Jaeyoon Choi <[email protected]> AuthorDate: 2026-08-10 01:51:30 +0000 Commit: Jaeyoon Choi <[email protected]> CommitDate: 2026-08-10 02:28:53 +0000 ufshci: release the CCB after sending a start stop unit command ufshci_sim_send_ssu() got a CCB from cam_periph_getccb() but never returned it. Each call leaked the CCB and one slot of the device's CCB allocation budget. When the budget runs out, the next cam_periph_getccb() waits forever and the suspend path hangs. Release the CCB while the periph lock is still held, as the other CAM periph drivers do.
