[patch 0/2] drivers/net/bonding sparse errors

[Ben Dooks]

drivers/net/bonding throws a large number of warnings
when compiling a kernel with sparse. These two patches
remove the easiest offenders to try and cut down the
number and see what is important.

[patch 1/2] drivers/net/bonding: sparse fixes for exported tables

[Ben Dooks]

[-- Attachment #1: bonding-fix-internal-include.patch --]
[-- Type: text/plain, Size: 1869 bytes --]

The following sparse warnings are being generated
because bonding.h is missing definitons for items
declared in bond_main.c but also used in bond_sysfs.h

Also export bond_dev_list as this is also declared
in bond_main but used elsewhere in drivers/net/bonding.

bond_main.c:105:20: warning: symbol 'bonding_defaults' was not declared. Should it be static?
bond_main.c:148:1: warning: symbol 'bond_dev_list' was not declared. Should it be static?
bond_main.c:162:22: warning: symbol 'bond_lacp_tbl' was not declared. Should it be static?
bond_main.c:168:22: warning: symbol 'bond_mode_tbl' was not declared. Should it be static?
bond_main.c:179:22: warning: symbol 'xmit_hashtype_tbl' was not declared. Should it be static?
bond_main.c:186:22: warning: symbol 'arp_validate_tbl' was not declared. Should it be static?
bond_main.c:194:22: warning: symbol 'fail_over_mac_tbl' was not declared. Should it be static?

[patch 2/2] drivers/net/bonding: move mutex decleration to header

[Ben Dooks]

[-- Attachment #1: bonding-fix-mutex.patch --]
[-- Type: text/plain, Size: 1662 bytes --]

Fix the sparse error generated by bonding_mutex being
declared in bond_sysfs.c but used in bond_main.c by
declaring an 'extern' in bond_main.c. Fix this by
moving the bond_main decleration to bonding.h.

The sparse warning is as follows:

bond_sysfs.c:67:14: warning: symbol 'bonding_mutex' was not declared. Should it be static?
