We are getting build failure with tilepro allmodconfig with the error:
drivers/iio/adc/fsl-imx25-gcq.c:236:4: note: in expansion of macro 'do_div'
do_div(priv->channel_vref_mv[reg], 1000);
^
include/asm-generic/div64.h:198:17: note: expected 'uint64_t *
{aka long long unsigned int *}' but argument is of type 'u32 *
{aka unsigned int *}'
Create a temporary variable of type u64 and use that in do_div.
