Hi Abhay,

and now starting with the coding style nitpicking ;)

Make it "if (!rbu_data.num_packets) {".

Don't forget the space between "while" and "(" and the "{"/"}" are not
needed.

We always put a space after ",".

Make it "(rbu_data.packet_write_count + length > rbu_data.packetsize)".

Make it "memcpy(ppacket->data + rbu_data.packet_write_count, ".

Why not:

	rbu_data.packet_write_count += length;
	if (rbu_data.packet_write_count == rbu_data.packetsize)
		rbu_data.packet_write_count = 0;

Forgot a space after "=" and after "...char*)".

> +	if (pbuf != NULL) {

Make it "if (!pbuf)",

Put a space after "...long)".

> +		if ((limit != 0) && ((img_buf_phys_addr + size) > limit)) {

Make it "if (!limit && img_bug_phys_addr + size > limit)"

> +			free_pages ((unsigned long)pbuf, *ordernum);

Space.

Space.

Use "(!pbuf)".

> +	if (rbu_data.packetsize == 0 ) {

Use "if (!rbu_data.packetsize)".

> +	if(newpacket == NULL) {

Use "if (!newpacket)".

> +	if(newpacket->data == NULL) {

Use "if (!newpacket->data)"

> +	if (rbu_data.packet_write_count == 0) {

Use this:

	if (!rbu_data.packet_write_count)
		if (!(rc = create_packet(length)))
			return rc;

> +	if ((rc = fill_last_packet(data, length)) != 0)

Use "if (!(rc = fill_last_packet(data, length)))".

> +		free_pages((unsigned long)newpacket->data, newpacket->ordernum);

Space.

> +	if (rbu_data.image_update_buffer == NULL)

Use "(!rbu_data.image_update_buffer)".

> +	free_pages((unsigned long)rbu_data.image_update_buffer,

Space.

> +		if ((size != 0) && (rbu_data.image_update_buffer == NULL)) {

Use "if (!size && !rbu_data.image_update_buffer)"

> +	image_update_buffer = (unsigned char *)get_free_pages_limited(size,

Space.

> +	if (image_update_buffer != NULL) {

Use "if (!image_update_buffer)".

> +		memset(rbu_data.image_update_buffer,0,

Space.

Spaces.

> +	if (size != 0)

Use "if (!size)".

> +	if (type == MONOLITHIC )

Space.

> +	if ( type == MONOLITHIC )

Spaces.

> +		size = sprintf(buf, "%lu\n",  rbu_data.bios_image_size);

Extra space not needed.

> +	if (type == MONOLITHIC ) 

Space.

> +	if (strlen(buf) >= 256 ) {

Space.

> +	if (type == MONOLITHIC ) {

Space.

> +	if (type == MONOLITHIC ) {

Space.

> +		if (fw_entry->size == 0 )

use "if (!fw_entry->size)".

> +				if (rc == 0) {

Use "if (!rc)".

> +		if ( rbu_data.packetsize != fw_entry->size )

Spaces.

> +		if ( rc == 0 )

Spaces.

> +static decl_subsys(dell_rbu,&ktype_dell_rbu,NULL);

Spaces.

> +        memset(rbu_dev, 0, sizeof (*rbu_dev));

No tab.

> +	if (type == MONOLITHIC)

Space.

> +		if (type == MONOLITHIC ) {

Space.

> +	if (rbu_dev != NULL) {

Use "if (!rbu_dev)".

What stand "dcd" for? Why not only "rbu_init"?

> +	if (rbu_download_mono == NULL) {	

Use "if (!rbu_download)".

> +	rbu_download_packet=  create_rbu_download_entry (PACKETIZED);

Wrong spaces.

> +	if (rbu_download_packet == NULL) {	

Use "if (!rbu_download_packet)".

> +	strncpy(rbu_device.bus_id,"firmware", BUS_ID_SIZE);

Space.

> +static __exit void dcdrbu_exit( void)

Why "dcd"?

Space vs tab clash.
