129dac3700 Staging: octeon: Avoid several usecases of strcpy

I replaced them with strscpy.

63350bdb38 staging: vhciq_core: replace snprintf with scnprintf
When the number of bytes to be printed exceeds the limit snprintf
returns the number of bytes that would have been printed (if there was
no truncation). This might cause issues, hence use scnprintf which
returns the actual number of bytes printed to buffer always

9a4c56be67 staging: wilc1000: avoid twice IRQ handler execution for each single interrupt
The IRQ handler(isr_bh_routine()) was called twice for each interrupt
from firmware. The data was read completely during the first call and
the second call was doing nothing.
Now changed the IRQ flag from ‘level’ to ‘edge’ trigger i.e
IRQF_TRIGGER_LOW to IRQF_TRIGGER_FALLING to avoid extra interrupt
trigger.

f6897deef4 iio: hid-sensor-attributes: Fix divisions for 32-bit platforms
The commit 473d12f763

  ("iio: hid-sensor-attributes: Convert to use int_pow()")

converted to use generic int_pow() helper. Though, the generic one returns
64-bit value and, in cases when it is used as divisor, it compels 64-bit
division from compiler.

In order to fix this, introduce a temporary 32-bit variable to hold the result
of int_pow() and use it as divisor afterwards.

In couple of cases, replace int_pow() with a predefined unit factors for time
and frequency.

e655b5b3a2 erofs: kill prio and nofail of erofs_get_meta_page()
As Christoph pointed out [1],
"Why is there __erofs_get_meta_page with the two weird
booleans instead of a single erofs_get_meta_page that
gets and gfp_t for additional flags and an unsigned int
for additional bio op flags."

And since all callers can handle errors, let's kill
prio and nofail and erofs_get_inline_page() now.

a5c0b7802c erofs: localize erofs_grab_bio()
As Christoph pointed out [1], "erofs_grab_bio tries to
handle a bio_alloc failure, except that the function will
not actually fail due the mempool backing it."

Sorry about useless code, fix it now and
localize erofs_grab_bio [2].

Fix as Christoph suggested [1] [2], "remove is_inode_fast_symlink

and
"Please just set the ops directly instead of obsfucating that in
