linux-next: scsi build failure

[Stephen Rothwell]

Hi James,

Today's linux-next build (x86_64 allmodconfig) failed like this:

In file included from drivers/message/fusion/mptscsih.c:66:
drivers/message/fusion/mptbase.h:715: error: 'KOBJ_NAME_LEN' undeclared here (not in a function)
In file included from drivers/message/fusion/mptbase.c:67:
drivers/message/fusion/mptbase.h:715: error: 'KOBJ_NAME_LEN' undeclared here (not in a function)

This is caused by commit 6146eaf4fb31588ecc72ab3c52c6b1f3e7602a7c
("[SCSI] mpt fusion : Adding FAULT Reset polling work") adding a usage of
KOBJ_NAME_LEN while commit 242d02fdc8d1764117a2e5fefd9e57b84d21bf40
("driver core: remove KOBJ_NAME_LEN define") from the driver-core tree
has removed it.  The change in that latter commit is to replace all
usages with 20, so I applied the following patch.  Something like this
could be integrated into the former commit.
