Subject: [PATCH 6.2 009/663] net: wwan: t7xx: do not compile with -Werror

From: Jiri Slaby (SUSE) <jirislaby@...nel.org>

[ Upstream commit 362f0b6678ad1377c322a7dd237ea6785efc7342 ]

When playing with various compilers or their versions, some choke on
the t7xx code. For example (with gcc 13):
 In file included from ./arch/s390/include/generated/asm/rwonce.h:1,
                  from ../include/linux/compiler.h:247,
                  from ../include/linux/build_bug.h:5,
                  from ../include/linux/bits.h:22,
                  from ../drivers/net/wwan/t7xx/t7xx_state_monitor.c:17:
 In function 'preempt_count',
     inlined from 't7xx_fsm_append_event' at ../drivers/net/wwan/t7xx/t7xx_state_monitor.c:439:43:
 ../include/asm-generic/rwonce.h:44:26: error: array subscript 0 is outside array bounds of 'const volatile int[0]' [-Werror=array-bounds=]

There is no reason for any code in the kernel to be built with -Werror
by default. Note that we have generic CONFIG_WERROR. So if anyone wants
-Werror, they can enable that.
