Subject: ide-floppy: add more debugging to idefloppy_pc_intr()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4c93067ea9e5eca9d975bec74dae641228ac1bbe;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ide-floppy: add more debugging to idefloppy_pc_intr()

Add more debugging to idefloppy_pc_intr() to match ide-tape's
idetape_pc_intr().

While at it:

* Correct the first debug message.

* Log device name with "DMA finished" message.

This is a preparation for adding generic ide_pc_intr() helper.
