Subject: spi: spidev_test: Fix input file check when transferring file
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e634b76caf830e802731e3491b24726883d1be98;p=linux-beck.git

spi: spidev_test: Fix input file check when transferring file

Check the input file fd instead of spidev fd.
The spidev fd is supposed to be OK otherwise the transfer_file() function
would not be called at all.
