Subject: [PATCH v2 10/19] scsi: aic94xx: Pass gfp_t flags to libsas event notifiers
Use the new libsas event notifiers API, which requires callers to
explicitly pass the gfp_t memory allocation flags.
Context analysis:
aic94xx_hwi.c: asd_dl_tasklet_handler()
-> asd_ascb::tasklet_complete()
== escb_tasklet_complete()
-> aic94xx_scb.c: asd_phy_event_tasklet()
-> aic94xx_scb.c: asd_bytes_dmaed_tasklet()
-> aic94xx_scb.c: asd_link_reset_err_tasklet()
-> aic94xx_scb.c: asd_primitive_rcvd_tasklet()
All functions are invoked by escb_tasklet_complete(), which is invoked
by the tasklet handler. Pass GFP_ATOMIC.
