[PATCH 3/5] Input: tsc2007 - fix minor coding style issues

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

Fix minor checkpatch warnings and checks across the tsc2007 driver:
document the mutex used to serialize I2C transfers between interrupt
handling and IIO reads, remove an unnecessary blank line following a
loop opening brace, and drop extraneous spacing after a cast.
