#     Merge tag 'driver-core-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
#     
#     Pull driver core updates from Greg KH:
#      "Here are all of the driver core and related patches for 4.19-rc1.
#     
#       Nothing huge here, just a number of small cleanups and the ability to
#       now stop the deferred probing after init happens.
#     
#       All of these have been in linux-next for a while with only a merge
#       issue reported"

WARNING: vmlinux.o(.text+0x44541d): Section mismatch in reference from the function docg4_attach_chip() to the function .init.text:init_mtd_structs()
The function docg4_attach_chip() references
the function __init init_mtd_structs().
This is often because docg4_attach_chip lacks a __init 
annotation or the annotation of init_mtd_structs is wrong.
