[PATCH RT 2/3] fscache: fix initialisation of cookie hash table raw spinlocks

[zanussi]

From: Gregor Beck <gbeck@xxxxxxxxxxxxxxxxxxxxx>

v5.4.143-rt64-rc2 stable review patch.
If anyone has any objections, please let me know.

-----------


The original patch, 602660600bcd ("fscache: initialize cookie hash
table raw spinlocks"), subtracted 1 from the shift and so still left
some spinlocks uninitialized.  This fixes that.
