Hi Punit Vara,
I cannot find build errors on my build machines.
According the log which you have posted before says *wilc is undeclared
in the function init_wilc_driver,
which means WILC_SPI is selected because one of SPI or SDIO should be
chosen at the moment.
Hence, struct wilc *wilc should be compiled together.
It looks like wilc1000 is compiled without SPI or SDIO.
Of course, there are many cases that I don't know, so you could let me
know the wilc1000 build configuration?
static int __init init_wilc_driver(void)
{
#ifdef WILC_SPI
This should be #ifndef WILC_SDIO
I will do this in the next patch series.
struct wilc *wilc;
#endif
But the large question remains of why do we have this variable here any
way?
As you pointed out, the variable is do-nothing for spi driver for now.
After reworking SPI driver, the wilc will be passed to SPI as spi drive data
like we already did in SDIO.
We have done this to remove extern variable g_linux_wlan which is primary
structure of wilc1000.
For now it is not used, but need it not to break the build.
static int linux_sdio_probe(struct sdio_func *func, const struct
sdio_device_id *id)
{
struct wilc_sdio *wl_sdio;
struct wilc *wilc;
PRINT_D(INIT_DBG, "probe function\n");
wl_sdio = kzalloc(sizeof(struct wilc_sdio), GFP_KERNEL);
if (!wl_sdio)
return -ENOMEM;
PRINT_D(INIT_DBG, "Initializing netdev\n");
local_sdio_func = func;
if (wilc_netdev_init(&wilc)) {
PRINT_ER("Couldn't initialize netdev\n");
kfree(wl_sdio);
return -1;
}
wl_sdio->func = func;
wl_sdio->wilc = wilc;
sdio_set_drvdata(func, wl_sdio);

glen lee.

How about this patch @Dan and @glen ,For me it does not create any
build error. For #ifndef WILC_SDIO that pointer *wilc is not
compiling so that creates the error.
As Dan said, I also think there are too many ifdefs now. We will remove the defines after
reworking SPI/SDIO modules.
For now, I cannot test since build error does not happens in my side. :(
Just in case, will this works for you?
config WILC1000_DRIVER
bool "WILC1000 support (WiFi only)"
depends on CFG80211 && WEXT_CORE && INET
+ depends on MMC || SPI
I will look into more about this later.
regards,
glen lee.
