There is no driver and it crashes the kernel, so just remove it. Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>

Subject: [PATCH] MIPS: BCM63XX: drop unused and broken DSP platform device
|
|
|
|
Trying to register the DSP platform device results in a null pointer
|
|
access:
|
|
|
|
[ 0.124184] CPU 0 Unable to handle kernel paging request at virtual address 00000000, epc == 804e305c, ra == 804e6f20
|
|
[ 0.135208] Oops[#1]:
|
|
[ 0.137514] CPU: 0 PID: 1 Comm: swapper Not tainted 4.14.87
|
|
...
|
|
[ 0.197117] epc : 804e305c bcm63xx_dsp_register+0x80/0xa4
|
|
[ 0.202838] ra : 804e6f20 board_register_devices+0x258/0x390
|
|
...
|
|
|
|
This happens because it tries to copy the passed platform data over the
|
|
platform_device's unpopulated platform_data.
|
|
|
|
Since this code has been broken since its submission, no driver was ever
|
|
submitted for it, and apparently nobody was using it, just remove it
|
|
instead of trying to fix it.
