tty: stop using alloc_tty_driveralloc_tty_driver was deprecated by tty_alloc_driver in commit7f0bc6a68ed9 (TTY: pass flags to alloc_tty_driver) in 2012.I never got into eliminating alloc_tty_driver until now. So we stillhave two functions for allocating drivers which might be confusing. Soget rid of alloc_tty_driver uses to eliminate it for good in the nextpatch.Note we need to switch return value checking as tty_alloc_driver usesERR_PTR. And flags are now a parameter of tty_alloc_driver.Cc: Richard Henderson (odd fixer:ALPHA PORT)Cc: Ivan Kokshaysky Cc: Matt Turner Cc: Geert Uytterhoeven Cc: "James E.J.

tty: don't store semi-state into tty driversWhen a tty driver pointer is used as a return value of structconsole's device() hook, don't store a semi-state into global variablewhich holds the tty driver.

6396bb22 - treewide: kzalloc() -> kcalloc()

Tue, 12 Jun 2018 21:03:40 +0000

treewide: kzalloc() -> kcalloc()The kzalloc() function has a 2-factor argument form, kcalloc(). Thispatch replaces cases of: kzalloc(a * b, gfp)with: kcalloc(a * b, gfp)as well as handling cases of: kzalloc(a * b * c, gfp)with: kzalloc(array3_size(a, b, c), gfp)as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp)This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp)though any constants defined via macros get caught up in the conversion.Any factors with a sizeof() of "unsigned char", "char", and "u8" weredropped, since they're redundant.The Coccinelle script used for this was:// Fix redundant parens around sizeof().@@type

tty: Remove redundant license textNow that the SPDX tag is in all tty files, that identifies the licensein a specific and legally-defined manner. So the extra GPL text wordingcan be removed as it is no longer needed at all.This is done on a quest to remove the 700+ different ways that files inthe kernel describe the GPL license text.
