[PATCH] spi/s3c64xx: Drop extra calls to spi_master_get in suspend/remove functions

[PATCH] spi/s3c64xx: Drop extra calls to spi_master_get in suspend/remove functions

[Guenter Roeck]

Suspend and resume functions call spi_master_get() without matching
spi_master_put(). The extra references are unnecessary and cause subsequent
module unload attempts to fail. Drop the calls.

(Cc'ed Mark Brown who is handling spi now)

Guenter, maybe you need to re-send this patch to Mark so that he can apply
;-)

Thanks.

Best regards,
Kgene.

Guess you are right - and I did copy Mark on my later patches. Mark, I just
bounced the patch to you, so you should have it now.
