MIPS: BCM63XX: drop unused and broken DSP platform device

2018-12-31T15:12:35Z

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.

MIPS: BCM63XX: Fix platform_devices id

There is only one watchdog and VoIP DSP platform devices per board, use -1 as the platform_device id accordingly. Signed-off-by: Florian Fainelli Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/3313/ Signed-off-by: Ralf Baechle
