Joe Perches 78110bb8dc staging: Remove unnecessary OOM messages
alloc failures already get standardized OOM
messages and a dump_stack.

For the affected mallocs around these OOM messages:

Converted kzallocs with multiplies to kcalloc.
Converted kmallocs with multiplies to kmalloc_array.
Converted a kmalloc/strlen/strncpy to kstrdup.
Moved a spin_lock below a removed OOM message and
removed a now unnecessary spin_unlock.
Neatened alignment and whitespace.

Ben Chan 129575f2a8 staging: gdm72xx: simplify alloc_tx_struct and alloc_rx_struct
This patch simplifies alloc_tx_struct and alloc_rx_struct in gdm_sdio.c
and gdm_usb.c by replacing kmalloc+memset with kzalloc and reorganizing
the code.

Devendra Naga 07ad99c9e3 staging: gdm72xx: use kzalloc to allocate usb_tx structure
the code under alloc_tx_struct does the allocation of usb_tx structure
using kmalloc, and memsets the allocated pointer, instead we can
directly use kzalloc so that the allocated memory is set with
zeros
