powercap: intel_rapl: remove redundant store to value after multiply
There is no need to store the result of the multiply back to variable value after the multiplication. The store is redundant, replace *= with just *. Cleans up clang scan build warning: warning: Although the value stored to 'value' is used in the enclosing expression, the value is never actually read from 'value' [deadcode.DeadStores] Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Rafael J.
