It maybe fixed by swapping positions of the arguments, i.e. ~(FOO | BAR) & flags....and type casting will be needed anyway here... I was thinking about this case drivers/i2c/busses/i2c-designware-common.c:420: dev->sda_hold_time & ~(u32)DW_IC_SDA_HOLD_RX_MASK ,quoted
but sda_hold_time there is unsigned.
That is needed because of the %d. Without the (u32), the expression is promoted to unsigned long and the compiler wants to see %ld. Guenter
