Subject[PATCH v2 31/35] x86/resctrl: Prefer alloc(sizeof(*foo)) idiom in rdt_init_fs_context()
Date
rdt_init_fs_context() sizes a typed allocation using an explicit
sizeof(type) expression, which checkpatch.pl complains about.

Since this code is about to be factored out and made generic, this
is a good opportunity to fix the code to size the allocation based
on the target pointer instead, to reduce the chance of future mis-
maintenance.

Fix it.

No functional change.
