[media] radio-si476x: vidioc_s* now uses a const parameter
vidioc_s_tuner, vidioc_s_frequency and vidioc_s_register now uses a constant argument. So, the driver reports warnings: drivers/media/radio/radio-si476x.c:1196:2: warning: initialization from incompatible pointer type [enabled by default] drivers/media/radio/radio-si476x.c:1196:2: warning: (near initialization for 'si4761_ioctl_ops.vidioc_s_tuner') [enabled by default] drivers/media/radio/radio-si476x.c:1199:2: warning: initialization from incompatible pointer type [enabled by default] drivers/media/radio/radio-si476x.c:1199:2: warning: (near initialization for 'si4761_ioctl_ops.vidioc_s_frequency') [enabled by default] drivers/media/radio/radio-si476x.c:1209:2: warning: initialization from incompatible pointer type [enabled by default] drivers/media/radio/radio-si476x.c:1209:2: warning: (near initialization for 'si4761_ioctl_ops.vidioc_s_register') [enabled by default] This is due to a (soft) merge conflict, as both this driver and the const patches were applied for the same Kernel version.
