      net: w5100: don't build spi driver without w5100 · b67d1df5
      Arnd Bergmann authored
      The w5100-spi driver front-end only makes sense when the w5100
      core driver is enabled, not for a configuration that only has w5300:
      
      drivers/net/built-in.o: In function `w5100_spi_remove':
      drivers/net/ethernet/wiznet/w5100-spi.c:277: undefined reference to `w5100_remove'
      drivers/net/built-in.o: In function `w5100_spi_probe':
      drivers/net/ethernet/wiznet/w5100-spi.c:272: undefined reference to `w5100_probe'
      drivers/net/built-in.o: In function `w5200_spi_init':
      drivers/net/ethernet/wiznet/w5100-spi.c:125: undefined reference to `w5100_ops_priv'
      drivers/net/built-in.o: In function `w5200_spi_readbulk':
      drivers/net/ethernet/wiznet/w5100-spi.c:125: undefined reference to `w5100_ops_priv'
      drivers/net/built-in.o: In function `w5200_spi_writebulk':
      drivers/net/ethernet/wiznet/w5100-spi.c:125: undefined reference to `w5100_ops_priv'
      drivers/net/built-in.o:(.data+0x3ed1c): undefined reference to `w5100_pm_ops'
      
      This adds an appropriate Kconfig dependency.

      bpf: avoid warning for wrong pointer cast · 266a0a79
      Arnd Bergmann authored
      Two new functions in bpf contain a cast from a 'u64' to a
      pointer. This works on 64-bit architectures but causes a warning
      on all 32-bit architectures:
      
      kernel/trace/bpf_trace.c: In function 'bpf_perf_event_output_tp':
      kernel/trace/bpf_trace.c:350:13: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
        u64 ctx = *(long *)r1;
      
      This changes the cast to first convert the u64 argument into a uintptr_t,
      which is guaranteed to be the same size as a pointer.

      of_mdio: make of_mdiobus_register_{device|phy}() *void* · b520bd07
      Sergei Shtylyov authored
      The results of of_mdiobus_register_{device|phy}() are never checked, so we
      can make  both these functions *void*...
