Subject: sata_sil24: Identify which card suffered IRQ status error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11838230da18cea5bc26a813b5425fe839248e93;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sata_sil24: Identify which card suffered IRQ status error

In machines with multiple Silicon Image 3124 and/or 3132 cards, there is no
way to tell which card is the culprit when the sata_sil24 interrupt handler
gets a bad status.
