ahci_platform: Remove unneeded ahci_driver.probe assignment
The driver is using platform_driver_probe() during initialization, so ahci_driver.probe hook is never used. But it causes the following (harmless, luckily) section mismatch: WARNING: vmlinux.o(.data+0x2fb20): Section mismatch in reference from the variable ahci_driver to the function .init.text:ahci_probe() This patch removes the ahci_driver.probe assignment, thus fixes the warning. p.s. Note that there's another patch[1] from Rene Bolldorf that tried to solve the same issue by __refdata annotation. __refdata says that this reference is actually OK, but in fact it is not OK, because dereferencing .probe() will cause problems. So the proper fix is to remove the assignment.
