Bhumika Goyal 7c0ddf06d2 ALSA: emu10k1: make snd_pcm_hardware const 
Make these const as they are only used during a copy operation.
Done using Coccinelle.

* Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
* Driver p16v chips
* Version: 0.25
*
* FEATURES currently supported:
* Output fixed at S32_LE, 2 channel to hw:0,0
* Rates: 44.1, 48, 96, 192.
*
* Changelog:
* 0.8
* Use separate card based buffer for periods table.
* 0.9
* Use 2 channel output streams instead of 8 channel.
* (8 channel output streams might be good for ASIO type output)
* Corrected speaker output, so Front -> Front etc.
* 0.10
* Fixed missed interrupts.
* 0.11
* Add Sound card model number and names.
* Add Analog volume controls.
* 0.12
* Corrected playback interrupts. Now interrupt per period, instead of half period.
* 0.13
* Use single trigger for multichannel.
* 0.14
* Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
* 0.15
* Force buffer_size / period_size == INTEGER.
* 0.16
* Update p16v.c to work with changed alsa api.
* 0.17
* Update p16v.c to work with changed alsa api. Removed boot_devs.
* 0.18
* Merging with snd-emu10k1 driver.
* 0.19
* One stereo channel at 24bit now works.
* 0.20
* Added better register defines.
* 0.21
* Integrated with snd-emu10k1 driver.
* 0.22
* Removed #if 0 ... #endif
* 0.23
* Implement different capture rates.
* 0.24
* Implement different capture source channels.
* e.g. When HD Capture source is set to SPDIF,
* setting HD Capture channel to 0 captures from CDROM digital input.
* setting HD Capture channel to 1 captures from SPDIF in.
* 0.25
* Include capture buffer sizes.
*
* BUGS:
* Some stability problems when unloading the snd-p16v kernel module.
* --
*
* TODO:
* SPDIF out.
* Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
* Currently capture fixed at 48000Hz.
*
* --
* GENERAL INFO:
* Model: SB0240
* P16V Chip: CA0151-DBS
* Audigy 2 Chip: CA0102-IAT
* AC97 Codec: STAC 9721
* ADC: Philips 1361T (Stereo 24bit)
* DAC: CS4382-K (8-channel, 24bit, 192Khz)
