Hello Maciej W. Rozycki,
The patch b98dfaf2b0a3: "defxx: DEFEA's ESIC port I/O decoding
cleanup" from Sep 25, 2014, leads to the following static checker
warning:
drivers/net/fddi/defxx.c:741 dfx_bus_init()
warn: odd binop '0x3 & 0xfffffffffffffffc'
drivers/net/fddi/defxx.c
729 val = PI_IO_CMP_M_SLOT;
730 outb(val, base_addr + PI_ESIC_K_IO_ADD_MASK_0_1);
731 val = (PI_ESIC_K_CSR_IO_LEN - 1) & ~3;
732 outb(val, base_addr + PI_ESIC_K_IO_ADD_MASK_0_0);
733
734 val = 0;
735 outb(val, base_addr + PI_ESIC_K_IO_ADD_CMP_1_1);
736 val = PI_DEFEA_K_BURST_HOLDOFF;
737 outb(val, base_addr + PI_ESIC_K_IO_ADD_CMP_1_0);
738
739 val = PI_IO_CMP_M_SLOT;
740 outb(val, base_addr + PI_ESIC_K_IO_ADD_MASK_1_1);
741 val = (PI_ESIC_K_BURST_HOLDOFF_LEN - 1) & ~3;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is just saying "val = 0" in a complicated way. It's not clear what
was intended...
742 outb(val, base_addr + PI_ESIC_K_IO_ADD_MASK_1_0);
743
regards,
dan carpenter
