Subject: MSI/powerpc: Use __read_msi_msg() instead of read_msi_msg()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1e8f4cc82eded0c3c97ef6e2f119782e42deda35;p=linux-beck.git

MSI/powerpc: Use __read_msi_msg() instead of read_msi_msg()

rtas_setup_msi_irqs() already has the struct msi_desc pointer required by
__read_msi_msg(), so call it directly instead of having read_msi_msg() look
it up from the IRQ.

No functional change.
