Subject: [PATCH 0/1] slimbus: fixes for v6.8

From: Srinivas Kandagatla <[email protected]>

Here are one fix in slimbus for 6.8, Could you queue
these for next possible rc.

This patch fixes one off bug in range of logical address assigned to the
device, which is why am sending for v6.8 rather than next release.

Thanks,
Srini

From: Christophe JAILLET <[email protected]>

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So change this change allows one more
device. Previously address 0xFE was never used.
