Subject: IB/core: Fix typo in the name of the tag-matching cap struct
Patch-mainline: Queued in subsystem maintainer repository
Git-repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
Git-commit: 78b1beb0998437107ed144b341fbe1252188916b
References: bsc#1046306 FATE#322942
The tag matching functionality is implemented by mlx5 driver
by extending XRQ, however this internal kernel information was
exposed to user space applications with *xrq* name instead of *tm*.
This patch renames *xrq* to *tm* to handle that.
Fixes: 8d50505ada72 ("IB/uverbs: Expose XRQ capabilities")
