staging: netlogic: Remove unnecessary error print
Kmalloc normally produces a backtrace when there is not enough memory.
So it is unnecessary to print an error message that provides only this
information. Hence, remove pr_error() from memory allocation check.

Staging: rtl8723bs: Change return type and type of local variable
rtw_startbss_cmd can return the result of calling rtw_enqueue_cmd, which
can return the result of calling _rtw_enqueue_cmd, but they all have
different return types (u8, u32, and sint, respectively).
As all of these functions return error codes, change all the return types
to int, in preparation for converting these functions to use standard
kernel error codes.
Also, remove extern from the function declaration to maintain Linux kernel
coding style.

The `insn_read` handler for the EEPROM subdevice on M-series boards
(`ni_m_series_eeprom_insn_read()`) currently ignores `insn->n` (the
number of samples to read) and assumes a single sample is to be read
into `data[0]`. Fortunately, the Comedi core ensures that `data[]` has
a length of at least 16 so there is no problem with array bounds.
The usual Comedi convention for `insn_read` handlers is to read the same
channel `insn->n` times into successive elements of `data[]` so let's do
that. (Each channel corresponds to a single EEPROM address.) In this
case, the data value comes from a local copy of the EEPROM contents.
Also, follow the usual Comedi convention and return `insn->n` from the
handler to indicate success (although any non-negative value will do).
