[PATCH AUTOSEL 6.5 07/31] ASoC: fsl-asoc-card: use integer type for fll_id and pll_id

[Sasha Levin]

From: Shengjiu Wang <shengjiu.wang@nxp.com>

[ Upstream commit 2b21207afd06714986a3d22442ed4860ba4f9ced ]

As the pll_id and pll_id can be zero (WM8960_SYSCLK_AUTO)
with the commit 2bbc2df46e67 ("ASoC: wm8960: Make automatic the
default clocking mode")

Then the machine driver will skip to call set_sysclk() and set_pll()
for codec, when the sysclk rate is different with what wm8960 read
at probe, the output sound frequency is wrong.

So change the fll_id and pll_id initial value, still keep machine
driver's behavior same as before.

[PATCH AUTOSEL 6.5 27/31] powerpc/85xx: Fix math emulation exception

[Sasha Levin]

From: Christophe Leroy <christophe.leroy@csgroup.eu>

[ Upstream commit 8e8a12ecbc86700b5e1a3596ce2b3c43dafad336 ]

Booting mpc85xx_defconfig kernel on QEMU leads to:

Bad trap at PC: fe9bab0, SR: 2d000, vector=800
awk[82]: unhandled trap (5) at 0 nip fe9bab0 lr fe9e01c code 5 in libc-2.27.so[fe5a000+17a000]
awk[82]: code: 3aa00000 3a800010 4bffe03c 9421fff0 7ca62b78 38a00000 93c10008 83c10008
awk[82]: code: 38210010 4bffdec8 9421ffc0 7c0802a6 <fc00048e> d8010008 4815190d 93810030
Trace/breakpoint trap
WARNING: no useful console

This is because allthough CONFIG_MATH_EMULATION is selected,
Exception 800 calls unknown_exception().

Call emulation_assist_interrupt() instead.
