/**
 * EVIOCGMASK - Retrieve current event mask
 *
 * This ioctl allows user to retrieve the current event mask for specific
 * event type. The argument must be of type "struct input_mask" and
 * specifies the event type to query, the address of the receive buffer and
 * the size of the receive buffer.
 *
 * The event mask is a per-client mask that specifies which events are
 * forwarded to the client. Each event code is represented by a single bit
 * in the event mask. If the bit is set, the event is passed to the client
 * normally. Otherwise, the event is filtered and will never be queued on
 * the client's receive buffer.
 *
 * Event masks do not affect global state of the input device. They only
 * affect the file descriptor they are applied to.
 *
 * The default event mask for a client has all bits set, i.e. all events
 * are forwarded to the client. If the kernel is queried for an unknown
 * event type or if the receive buffer is larger than the number of
 * event codes known to the kernel, the kernel returns all zeroes for those
 * codes.
 *
 * At maximum, codes_size bytes are copied.
 *
 * This ioctl may fail with ENODEV in case the file is revoked, EFAULT
 * if the receive-buffer points to invalid memory, or EINVAL if the kernel
 * does not implement the ioctl.

 * This ioctl is the counterpart to EVIOCGMASK. Instead of receiving the
 * current event mask, this changes the client's event mask for a specific
 * type.  See EVIOCGMASK for a description of event-masks and the
 * argument-type.
 *
 * This ioctl provides full forward compatibility. If the passed event type
 * is unknown to the kernel, or if the number of event codes specified in
 * the mask is bigger than what is known to the kernel, the ioctl is still
 * accepted and applied. However, any unknown codes are left untouched and
 * stay cleared. That means, the kernel always filters unknown codes
 * regardless of what the client requests.  If the new mask doesn't cover
 * all known event-codes, all remaining codes are automatically cleared and
 * thus filtered.
 *
 * This ioctl may fail with ENODEV in case the file is revoked. EFAULT is
 * returned if the receive-buffer points to invalid memory. EINVAL is returned

	171	* EVIOCGMASK - Retrieve current event mask
	172	*
	173	* This ioctl allows user to retrieve the current event mask for specific
	174	* event type. The argument must be of type "struct input_mask" and
	175	* specifies the event type to query, the address of the receive buffer and
	176	* the size of the receive buffer.
	177	*
	178	* The event mask is a per-client mask that specifies which events are
	179	* forwarded to the client. Each event code is represented by a single bit
	180	* in the event mask. If the bit is set, the event is passed to the client
	181	* normally. Otherwise, the event is filtered and will never be queued on
	182	* the client's receive buffer.
	183	*
	184	* Event masks do not affect global state of the input device. They only
	185	* affect the file descriptor they are applied to.
	186	*
	187	* The default event mask for a client has all bits set, i.e. all events
	188	* are forwarded to the client. If the kernel is queried for an unknown
	189	* event type or if the receive buffer is larger than the number of
	190	* event codes known to the kernel, the kernel returns all zeroes for those
	191	* codes.
	192	*
	193	* At maximum, codes_size bytes are copied.
	194	*
	195	* This ioctl may fail with ENODEV in case the file is revoked, EFAULT
	196	* if the receive-buffer points to invalid memory, or EINVAL if the kernel
	197	* does not implement the ioctl.

	206	* type. See EVIOCGMASK for a description of event-masks and the

	211	* the mask is bigger than what is known to the kernel, the ioctl is still
	212	* accepted and applied. However, any unknown codes are left untouched and
	213	* stay cleared. That means, the kernel always filters unknown codes
	214	* regardless of what the client requests. If the new mask doesn't cover
	215	* all known event-codes, all remaining codes are automatically cleared and
	216	* thus filtered.
