Kishon Vijay Abraham I 7a360e546a phy: ti: Fix missing sentinel for clk_div_table ... commit 6d1e6bcb31 upstream. _get_table_maxdiv() tries to access "clk_div_table" array out of bound defined in phy-j721e-wiz.c. Add a sentinel entry to prevent the following global-out-of-bounds error reported by enabling KASAN.
