Subject: afs: remove manual O_SYNC handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=027cf316afff03d310281709314fbc0899984759;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

afs: remove manual O_SYNC handling

generic_file_aio_write already calls into ->fsync to handle O_SYNC/O_DSYNC.
Remove the duplicate manual invocation.
