misc: panel: properly restore atomic counter on error path

2017-11-18T10:11:07+00:00

commit 93dc1774d2a4c7a298d5cdf78cc8acdcb7b1428d upstream. Commit f4757af ("staging: panel: Fix single-open policy race condition") introduced in 3.19-rc1 attempted to fix a race condition on the open, but failed to properly do it and used to exit without restoring the semaphore. This results in -EBUSY being returned after the first open error until the module is reloaded or the system restarted (ie: consecutive to a dual open resulting in -EBUSY or to a permission error). Fixes: f4757af85 # 3.19-rc1 Cc: Mariusz Gorski Signed-off-by: Willy Tarreau [wt: driver is in staging/panel in 4.4] Signed-off-by: Greg Kroah-Hartman
