Fix the following sparse context imbalance regression introduced in a patch that fixed sleeping function called from invalid context bug. kbuild test robot reported on: tree/branch: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-linus Regressions in current branch: drivers/usb/usbip/stub_dev.c:399:9: sparse: sparse: context imbalance in 'stub_probe' - different lock contexts for basic block drivers/usb/usbip/stub_dev.c:418:13: sparse: sparse: context imbalance in 'stub_disconnect' - different lock contexts for basic block drivers/usb/usbip/stub_dev.c:464:1-10: second lock on line 476 Error ids grouped by kconfigs: recent_errors ├── i386-allmodconfig │ └── drivers-usb-usbip-stub_dev.c:second-lock-on-line ├── x86_64-allmodconfig │ ├── drivers-usb-usbip-stub_dev.c:sparse:sparse:context-imbalance-in-stub_disconnect-different-lock-contexts-for-basic-block │ └── drivers-usb-usbip-stub_dev.c:sparse:sparse:context-imbalance-in-stub_probe-different-lock-contexts-for-basic-block └── x86_64-allyesconfig └── drivers-usb-usbip-stub_dev.c:second-lock-on-line This is a real problem in an error leg where spin_lock() is called on an already held lock. Fix the imbalance in stub_probe() and stub_disconnect().
