      [ 444.853098] BUG: KASAN: global-out-of-bounds in param_get_int+0x77/0x90
      [ 444.853111] Read of size 4 at addr ffffffffc16c9220 by task cat/2105
      ...
      [ 444.853442] The buggy address belongs to the variable:
      [ 444.853443] max_idle+0x0/0xffffffffffffcde0 [intel_powerclamp]

There is a mismatch between the param_get_int and the definition of
max_idle.  Replacing param_get_int with param_get_byte resolves this
issue.
