Don't cast parameter to unsigned long pointer in the bit operations. Note, new compilers might warn on this line for potential outbound access. *) it seems a dead code, so remove it all for good Fixes: 13d19498b044 ("GRU Driver: driver internal header files") Acked-by: Dimitri Sivanich Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20220214153958.9721-1-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/misc/sgi-gru/grutables.h b/drivers/misc/sgi-gru/grutables.h index e4c067c61251..5efc869fe59a 100644 --- a/drivers/misc/sgi-gru/grutables.h +++ b/drivers/misc/sgi-gru/grutables.h @@ -530,12 +530,6 @@ struct gru_blade_state { for ((i) = (k)*GRU_CBR_AU_SIZE; \ (i) < ((k) + 1) * GRU_CBR_AU_SIZE; (i)++) -/* Scan each DSR in a DSR bitmap.
