scsi: aic7xxx: Remove unnecessary NULL checks before kfree
There are a number of places in the aic7xxx driver where a NULL check is performed before a kfree(). However, kfree() already performs NULL checks so this is unnecessary. Remove the checks. Issue identified with Coccinelle. Link: https://lore.kernel.org/r/20200403164712.49579-1-alex.dewar@gmx.co.uk Signed-off-by: Alex Dewar <alex.dewar@gmx.co.uk> Signed-off-by: Martin K.
