#     cxl: Fix wrong comparison in cxl_adapter_context_get()
#     
#     Function atomic_inc_unless_negative() returns a bool to indicate
#     success/failure. However cxl_adapter_context_get() wrongly compares
#     the return value against '>=0' which will always be true. The patch
#     fixes this comparison to '==0' there by also fixing this compile time
#     warning:
#     
#     	drivers/misc/cxl/main.c:290 cxl_adapter_context_get()
#     	warn: 'atomic_inc_unless_negative(&adapter->contexts_num)' is unsigned
#     
#     Fixes: 70b565bbdb91 ("cxl: Prevent adapter reset if an active context exists")
